Our ethos says that treatment should be phased to deliver prevention and disease control before attempting to repair the damage with restorative dentistry. The prevention and disease control is the main task of the hygienist and therapist service.

A brief summary of their roles appears in the downloadable PDF.

The hygienists provide control of periodontal disease by performing root surface debridement, root planing and irrigating periodontal pockets with the aim of reducing inflammation. They will advise on an appropriate oral hygiene regime for you to use at home.

In addition to this, the therapists provide routine fillings and operative treatments for carious areas

which require attention. The preventative nurse can perform plaque, saliva and bacterial tests and apply the more concentrated fluorides for non-operative treatment of early caries or in older patients to in-operable root caries lesions. This can also help those patients with sensitive roots.

Do you dread coming to the dentist? If you, like many others, are a ‘dental phobic’ then we believe we can help you.

For those on the lesser end of the phobic spectrum, sometimes just a friendly, gentle manner can be enough to calm your anxiety. All of our dental team are fully trained in dealing with anxious patients and we are more than happy to take a slow sympathetic approach to all treatment.

For those who need more of a helping hand, we offer private treatment under intravenous sedation. For the majority of sedation patients, we use Midazolam intravenously

(injection in the back of the hand or in the arm) to help calm your nerves and help you feel more at ease with having dental treatment. The procedure is very safe. You will remain awake, but will feel a little sleepy. You will be so relaxed that you will be mostly unaware of the treatment taking place, and chances are that you will forget the majority of the procedure by the next day (Midazolam has a mild amnesic effect).

We are able to offer any routine treatments under sedation, including simple fillings, root canal, tooth extractions and ceramic reconstruction. We also offer implants under sedation. Contact our dental team for more information.

There are three different options for the treatment you receive through our practice, NHS, Private Care package and direct charges by our practice. Please read the following if you would like to find out more information.

NHS Care

nhsAt The Oral Health Clinic we offer NHS care but the amount of care we can offer is limited by NHS England. This means we have to ration it on a monthly basis. The NHS is an ‘essential service’ and there are strict guidelines on how often we can review patients. The main function is the provide access to dental care when necessary. All NHS charges are beyond our control. The fees are like ‘taxes’ and have to be collected on the day or paid in advance.

Private Care Packages

We are also a Denplan Excel Accredited Practice which means we are inspected annually and comply with their codes of practice. We offer both Dental Essentials and Denplan Care. These plans are paid by monthly direct debit.


Patients can also just opt to pay privately for any treatment direct to our practice.

Fees are based on time and costs for individual items are misleading. Please ask reception for an idea of costs.

In Summary

The most obvious difference is that in the NHS, patients do not have a ‘dentist’ as such; they are all patients of ‘NHS England’ and since April 2006 there has been no continuing care concept. We disagree with this and prefer the on-going commitment that Denplan or Private contract provides.

You can download our Denplan Vs NHS PDF from the free resources page for a more detailed explanation about the differences between NHS and Denplan or private care.

Implants have been used extensively in Europe over the last 15 years. Five years ago, Northern European countries provided 20 times as many implants as the UK and Spain, 5 times. Over 1 million were done in Europe last year!

Our Implant surgery team is as follows:

John Duthie BDS MGDS;RCS ( Eng.) who will now provide the superstructures i.e. the crowns, bridges and over-dentures which restore the teeth to a very high standard.

Mr Paul Swanson BDS MFDGP(UK) DipImpDent;RCS(Eng.) MSc.(Imp.) who has the expertise in the placement of the leading implant types and performs any necessary bone grafting, sinus lifts or augmentation procedures. Paul works here at the practice on Mondays when joint clinics are arranged. Any CT scans necessary are also provided in South Liverpool.

• Very complex cases are referred to Carl Jones, a Consultant Maxillo-Facial surgeon who helps with the more complex surgery involving hip grafts, mandibular reconstruction moving nerve supplies or all three. These cases are usually victims of trauma or tumours. Chris Butterworth is the Merseyside Consultant in major oral rehabilitation

• We often arrange second opinions to check our diagnosis and treatment plan. We also work with Ashok Sethi in Harley St if the highest level of international expertise is required.

P1040539Whiter teeth, everybody wants them. And why not?

Your smile is the first thing others notice about you. It says more about you than any other feature.

Tooth whitening can be the simplest, kindest and most affordable way of enhancing your smile. Many people look and feel years younger after the treatment. Here at Duthie Wyatt and Duthie we have paid particular attention to the developments in tooth whitening agents and techniques for many years. In 2005 Dr Marie-Louise Duthie embarked on the tooth whitening expert Dr Linda Greenwall’s course held at the Royal College of Physicians in London.

Since then the practice has tried a number of different tooth whitening systems and with 12 years experience in the area we feel we have found an excellent solution for our patients.

When it comes to tooth whitening there is no quick fix. Your teeth have darkened over decades of staining agents found in food and beverages. Lasers and one hour treatments have been found to be far less effective that progressive night-bleaching over a sustained period of time. We at Duthie Wyatt and Duthie would agree that this seems to be the case in our experience.

We have managed to find one lab in the UK that can make the quality of vacuum sealed tray that we require to prevent the bleaching agent diluting.


with saliva. We have found the best results with Optident White tooth whitening agents using them under a specific prescription increasing the concentration as you go through the course. We expect most patient to commit to a 3-4 week period of whitening. In our experience 2 weeks is not sufficient to achieve the desired result.P1040547

Sensitivity must be expected during the procedure, this sensation tends to die off within a few days of completing the course. Once they have been whitened you will need to wear you trays and top up 3-6 nights per year to maintain the appearance.

It is very important that children learn how to look after their teeth from an early age to ensure that they can have a healthy smile for life. We therefore recommend that your child visits the dentist before they are 2 years of age so they can get used to the dental surgery and so we can advise on healthy eating and tooth brushing. We have a very caring approach here at The Oral Health Clinic; our aim is to make your child’s dental appointment comfortable and fun.

Maintaining good oral health is very important for your child’s general health too. Dental problems can cause difficulty eating and drinking as well as affecting sleep and concentration. Although children will loose their first set of teeth, it is still incredibly important that they are well looked after. These teeth allow your child to eat and speak correctly, as well as maintaining space for the permanent teeth to follow.

As your child grows we continue to offer preventative advice and keep a check on dental health and development. When children are at high risk of developing decay we can apply fluoride varnish to their teeth. This provides extra protection against decay when used in addition to regular brushing with fluoride toothpaste. This process may need to be repeated every 3-6 months depending on the need of your child.

We may also decide that the application of fissure sealants are necessary to prevent dental decay. A fissure sealant is a safe and painless way of protecting teeth by covering the grooves (fissures) in the back teeth where food and bacteria can become trapped. The sealant is a white, plastic coating that acts a shield in these areas where dental decay is most common.

If your child does experience dental decay we will be able to treat this quickly in a gentle and effective way. We can also refer to an orthodontic specialist if teeth become poorly aligned and braces are required.

Children’s dentistry is funded by the NHS up to the age of 18.

Cosmetic Dentistry is a popular term for making teeth look ‘nice’. For us, it conjures up the image of the over-white California big tooth smile which is reminiscent of ‘fridge doors’ and bright red lipstick.

We prefer the term ‘Aesthetic Dentistry’.

Most of our patients do not want everyone to know they have had crowns and veneers. They want their teeth to look ‘nice’ but ‘natural’.

It is now possible to use ‘aesthetic materials’ for all fillings, veneers, crowns, bridges and implants.

In 1987 Mr Duthie was introduced to a milled ceramic material which would do all these things. Unfortunately the technology at the time was costing so much that each restoration would have cost over £1000 just to make! It took a German and a Swiss scientist 15 years to perfect a commercially viable method of using this material to produce restorations which could be superior to anything else available. In 2003, the advent of the Pentium 4 computers allowed laser camera and milling technology previously used only in the aerospace industry to become commercially viable and we started using this immediately.

The restorations are called CEREC and we use them for 95% of the aesthetic dentistry we do which requires a laboratory technique. They are made on the premises and we finish the artwork by hand in the surgery. This gives us the ability to match the teeth as well as possible. We use the material for large restorations in the back teeth as most patients prefer the natural colour. Ceramic is used for the insides of jet engines, brake pads and the tiles on the space shuttle. In the correct dimension and designs it is strong enough to withstand the biting forces in back teeth. Unlike conventional porcelains, the material has the same wear resistance as enamel so is ideal for rebuilding bites and also for single teeth.

Paramount in the provision of good dental practice is the concept of ‘minimal interventive dentistry’.
Many ‘cosmetic’ restorations can be done with the newer nano-composites. These are ‘direct’ restorations and cheaper than CEREC. Once a defect has reached a certain size then CEREC becomes necessary but it has the advantage of complying with the concept of ‘minimal intervention’ by being designed to replace only the missing part without further destructive drilling

CEREC… What are CEramic REConstructions?

CEREC is a CAD / CAM system which enables us to use the best materials for the reconstruction of teeth damaged by tooth decay or trauma.


• The restorations are milled from a prefabricated solid block of the highest quality ceramic, resin or zirconium (artificial diamond)

• There are no impressions needed

• The teeth are scanned with a laser camera which records the 3D shape

• This is done to an accuracy of 10 microns

• Our milling machine mills to an accuracy of 25 microns

• This is the diameter of a human hair; and gives much improved accuracy

It’s said that we all end up with the face that we deserve. Laughter lines, crows feet, sagging jaw lines and numerous other manifestations are unfortunately part of our body’s ageing process. Looking forever 21 is not an option and ultimately no amount of facial enhancement, surgical or nonsurgical, can keep the sands of time at bay. But, it can be slowed down!

Our faces are unique, they are the portrait of our personality and no two are totally identical. Therefore, they have to be treated individually, with sensitivity and care. Successful restoration, as with all works of art, is a highly professional and skilled procedure. With the correct advice, product choice and technical expertise, Facial Aesthetics can create and maintain a fresh and youthful appearance.

My training and career as a Dental Surgeon (qualified 2002) gives me extensive knowledge of the facial anatomy. This has stimulated my interest in Facial Aesthetics and I completed separate professional training in this field, at the Royal Society of Medicine and the Royal College of Physicians in 2008.

I specialise in the use of Botulinum Toxins and facial fillers, which I use in traditional therapeutic cases as well as cosmetic enhancement. My interest in this field is extensive, and I embarked on a postgraduate research MSC in non-surgical Facial Aesthetics at the University of Central Lancashire 2011. I now also hold a Post-Graduate Diploma in Non-Surgical Facial Aesthetics.

Having the highest level of qualifications available in this field is extremely important to me, as I believe it gives my patients even greater confidence in the treatments I offer.

I have personal experience of the benefits of each and every treatment that I offer to my patients; do only to others as you would do to yourself! My belief is that ‘light touch’ is the preferred methodology for truly successful rejuvenation.

The ‘wind tunnel’ effect or the permanently startled expression is not my idea of professional facial enhancement. I want my patients to leave my surgery with a naturally refreshed and younger appearance – the signature look for my practice!

Detailed assessment and practical advice is key to outstanding results. There is a natural order to how our necks and faces age, certain areas deteriorate more rapidly than others; for instance in our fourth decade (30-40) the first signs of ageing tend to show, with the splitting and dropping of the malar complex (Cheek contour). Loss of cheek volume occurs and the tissues descend, helping to form the naso-labial fold. My objective is to make my patients aware of the treatment areas and procedures required to achieve the most effective results. Cheek augmentation early, rather than the filling of Naso-labial folds, restores the natural balance very effectively before nasolabial fold intervention is necessary.

As a medical professional my concern is first and foremost for the health and wellbeing of my patients. If I believe that there is no benefit to be gained from a specific procedure, rest assured I will be open and honest with my advice. All Facial Aesthetic procedures are carried out by myself within the sterile clinical environment of my own surgery, with strict cross-infection controls and medical protocols in place.

We are CQC registered and have been inspected.

What I can do for you

My specialist range of non-surgical treatments are designed to help my patients look and feel their best. Procedures are carried out only after consultation and are virtually pain-free, with a minimum of down time.

To safeguard the health and wellbeing of my patients I use only high-quality clinically approved and licensed products. Non-Surgical Face Aesthetic procedures not only visibly improve appearance, but they have been proven to have psychological benefits such as improving mood and increasing levels of self-esteem.

Wrinkle softening procedures are straightforward and can even be done during a lunch hour, the only subsequent effects being slight redness around the treated areas. I use Botulinum Toxin to treat the pre-selected areas. The process of smoothing out lines and wrinkles takes 7-14 days before the full effects of each treatment are revealed. The results last 3-4 months.


To soften and smooth out forehead wrinkles and frown lines resulting in a more youthful appearance, I use a substance called Botulinum Toxin. Popular brands include Azzalure® and Botox®. These are tried and tested products which have been used safely and effectively in the medical world for well over 25 years.


Botulinum Toxin is also used to smooth out the wrinkles known as ‘crows feet or laughter lines’ around the eyes. This is a sensitive area and I am able to treat this region relatively painlessly using advanced application techniques.

Cheek Augmentation

As I stated earlier the cheek mid-face region is one of the first areas to show deterioration. Restoring this volume helps to prevent early naso-labial fold development. Hyaluronic acid gel fillers are used, the added beauty of these products is that they are not permanent and can be dissolved by an enzyme if necessary.

Lips and Mouth creases

Enhancing the shape and fullness of the lips by softening the creases sometimes known as ‘lipstick lines or smokers lines’ around the mouth achieves a significantly younger look to the lower part of the face. Following the application of local anaesthetic to the region I can safely and painlessly inject a special gel-like product in the lips and borders. The result is instant rejuvenation, the effects of which can last between 6-18 months depending on the products used. Swelling and occasional bruising may be experienced.

Nose to mouth and Marionette lines

As we get older this area is particularly prone to creasing. The corners of the mouth begin to turn downwards and loss of volume in these areas can be one of the most concerning and distressing for women. After applying a local anaesthetic I can inject fillers using an advanced cannula technique to ‘plump up’ the tissue and reduce the appearance of lines, resulting in a smoother, more youthful look. Cannulas help to prevent any significant bruising.

Skin Rejuvenation treatments

Percutaneous Collagen Induction therapy: Medical Micro-needling This treatment helps to reduce the depth of fine lines and wrinkles, it can also produce fantastic results for patients who suffer with acne scarring. A course of treatment is required. Numbing cream is applied to the face. The treatment takes around 30 minutes. You should expect to be slightly flushed in the face for the next 24 hours, and expect some dryness of the skin for the week or two following the procedure. Repeat courses are recommended every 6 weeks until a satisfactory result is reached; the number of treatments required will vary dependant upon the severity of any scarring. This treatment requires you to use SPF50 on your skin to protect the regenerating tissue beneath from harmful UV radiation effects. The face should be kept out of direct sunlight. This treatment is usually carried out during winter months, as it’s best to avoid times when a spell in the sunshine is planned.

Chemical Peels

I have taken a great deal of time researching the best agents to use on the skin surface for a number of different concerns. I have chosen the SkinMed range of Enerpeels as they have evidence based scientific data. The peels range from light to medium depth peels helping with active acne, reduce fine lines and wrinkles, age related pigmentation, brown spots and flushed faces.

Small changes – big benefits

We are all aware of the bad effects that sun exposure, tobacco, alcohol and poor eating habits have on our general health, but as we age this shows on our faces. Small changes can make a big difference, UV exposure has by far the biggest external impact on the ageing of the face. It is recommended that a Factor 50 SPF should be used at all times, even in the UK. Stopping smoking, a healthier diet and gentle exercise can help to slow down the ageing process and even contribute to the longevity of Facial Aesthetic treatments.

Your Invisalign treatment consists of a series of nearly invisible, removable aligners that you change every two weeks for the next set of aligners. Each aligner is individually manufactured for your teeth, and your teeth only. As you replace each aligner, your teeth will move – little by little, week by week – until they have straightened to the final position prescribed by your dental practitioner.

What’s more, a virtual 3D treatment plan (ClinCheck© treatment plan) shows the series of movements your teeth will go through over the course of the treatment. This allows you to see upfront what your teeth are expected to look like at the end of the treatment. From the results of the ClinCheck treatment plan, your custom-made, clear aligners are produced especially for you.

If you’re ready for a smile that transforms your appearance, Invisalign is your answer. Although there are many choices out there, no other treatment works as comfortably as Invisalign.

Invisalign is the best way to transform your smile without interfering with your day-to-day life. Check out the benefits below:
