The levels of Invisalign provider in London

Invisalign has become a mainstream orthodontic appliance and deciding on an Invisalign provider can be time-consuming and a difficult job especially in big cities with numerous providers.

Choosing the right Invisalign Provider will provide security and peace of mind that your smile will be the one to keep for the rest of your life!


Experience and qualifications can vary widely between Invisalign providers which are categorised in 5 different levels, based on their experience in providing Invisalign treatments.

The levels of Invisalign provider

Level 1 – Bronze Provider

A bronze provider would have completed up to 10 cases per year.

Level 2 – Silver Provider

A silver provider would have completed between 11 and 20 Invisalign cases per year.

Level 3 – Gold Provider

A gold provider would have completed between 21 and 50 Invisalign cases per year.

Level 4 – Platinum Provider

A Platinum provider would have completed between 51 and 150 Invisalign cases per year.

Level 5 – Diamond Provider

A diamond provider would have provided more than 151 Invisalign cases per year. This is the highest level an Invisalign provider can obtain. The higher levels are usually obtained by bigger practices however a patient would be better off looking at the individual doctor’s achievements.

Levels of Invisalign provider


Is the provider’s level the most important thing?

For every patient, the most important thing is the certification of the provider. Look for certifications from established universities and institutions in the United Kingdom. Having a specialist orthodontist providing you with treatment ensures that they can accurately diagnose your problem and know the right course of action to take.

Naturally, apart from certifications and qualifications, experience goes a long way.

What is the first step to have Invisalign treatment?

It is important to schedule an initial consultation with an Invisalign provider. This provides a great opportunity to get to know them and what they can do for you. The provider would outline the benefits and risks and outline any difficulties or restrictions that might be met along your treatment path.

The consultation should be with the Invisalign provider himself/herself. Having a consultation with a coordinator or therapist might not provide you with the answers to all the questions you might have.

Missing Teeth – Hypodontia Treatment

Some people present with missing teeth, a condition known medically as, Hypodontia.

Hypodontia condition affects 2-6% of the population, people with this condition usually self-refer themselves as they are aware that some teeth are missing or the dentist usually refers them for specialised orthodontic toot movements. Orthodontic tooth movements is usually needed to make space or decrease the space available. The main reason for missing teeth is commonly due to failure of formation of the teeth during their formation stages.

This condition can present itself as 1 missing tooth in the whole mouth to many missing teeth which can be more obvious even to the untrained eye.

Is hypodontia hereditary?

Most times this condition is hereditary, however it can occur in children without a family history. Siblings are usually affected in a similar manner however it can also affect one of the siblings, for parents with more than one child.

It most commonly affects the adult teeth, but in rare cases the ‘baby’ or ‘milk’ teeth are also missing.

Is hypodontia linked to other diseases?

The best advice is that you ask your general dentist about the condition as it might be part of other medical conditions.

Hypodontia is often associated with other dental anomalies such as small-sized teeth, delayed eruption of teeth, ectopic teeth (teeth developing in the wrong place) and lack of jaw bone which is very relevant in case the patient needs dental implant placement during adulthood.

Treatment of missing teeth and hypodontia

It is recommended that you look for specialists that can manage this condition. As mentioned above, a very important team member, is the specialist in orthodontics, which is the initial step in achieving a great smile.

How we can help at 128 Harley Street, London W1

  • At the initial assessment appointment you are seen by Dr Stefan Abela and a detailed plan will be outlined for you.
  • Other team members that have expertise in replacing tooth gaps and placing dental implants will play a vital role following the orthodontic treatment.
  • Dr Milisha Chotai will guide you through this process once you are ready to have the gaps filled with prosthetic teeth.
  • There could be an interim period where dentures are used to allow the teeth to “settle”, usually followed by bridges and/or dental implants.
  • The majority of implants are placed after skeletal growth is completed.  They may require bone grafting surgery to develop the site prior to implant placement.

5 Myths about Permanent Teeth Replacements

(i.e. Dental Implants)

1. “Dental implant treatment is painful”

Scientific research has shown that tooth removal is perceived as more painful than dental implant treatment.

2. “Dental Implants are expensive”

Dental implants are cost-effective in the long term. Removable dentures do not contribute to efficient chewing. The risk of breaking your remaining teeth increases significantly as a result of denture wear. Fixed dental bridges are difficult to clean and destructive on teeth. Bridged teeth are at higher risk of being lost.

3. “Dental implants can catch dental decay”

Dental implants are made of strong titanium. It cannot catch dental decay.

4. “Dental implants can be fitted and forgotten”

Dental implants require the highest level of home-care.

5. “Dental implants can be placed at any time after loosing teeth”

Losing teeth will subsequently result in the loss of stimulation to the jaw bone. This in turn causes shrinkage of the bone. Bone loss is rapid in the first 6 months following tooth loss. Dental implants are therefore best placed shortly after tooth removal. Delaying implant placement will most likely result in further jaw bone loss and the need for bone- building procedures.

Mouthwash will boost the strength of your enamel and can protect your teeth against tooth decay. It is best to avoid eating/drinking/rinsing for one hour following the use of mouthwash. I usually recommend the use of mouthwash after breakfast and before bed-time.

The myth of corsodyl resolved..
Most of us have seen the corsodyl commercial where promises are given that it will treat everything! Corsodyl mouthwash should only be used for a limited time when prescribed by a dentist. Long-term use of corsodyl mouthwash can cause staining of teeth and change in taste sensations.

Which mouthwash is the best?
There are so many mouthwashes out there! To make it simple:
– Choose a mouthwash that contains fluoride
– I prefer alcohol free mouthwashes as they are not as strong and do not dry the mouth
– I love fluoriguard mouthwash. It has a high concentration of fluoride and it tastes nice leaving a nice fresh feeling after use.
– Use what you feel comfortable with!

Bad Breath

How to combat Bad Breath

Bad breath can be both embarrassing and problematic. Some people are aware of their bad breath and some are not. Patients usually approach the topic because their partner or spouse have brought it up.

 What causes bad breath?

The most common cause of bad breath is the accumulation of bacteria on your teeth, gums and tongue. These bacteria are also responsible for causing tooth decay and gum problems.

Smoking and strong drinks, such as coffee and alcohol can also cause bad breath. Medical conditions such as mouth dryness, diabetes, tonsillitis, sinusitis and gastro-oesophageal reflux disease are also reasons for bad breath. Certain medications including nitrates, chemotherapy medication and tranquiliser can also cause this problem.


  • Practice good dental hygiene with tooth brush and cleaning between teeth

  • Use a tongue scraper

  • CB12 is a mouthwash targeted at bad breath

  • Have regular dental check ups to ensure that problems are picked up and treated early.

  • Drink water when thirsty rather than strong drinks

A Dentist’s Secret to a Healthy Smile

We are often asked about what products we recommend. We thought we would compile a list of the products that we use on a daily basis.

Feel free to contact us should you have any further questions….we are always happy to help!


1.Oral B satin floss coated with fluoride

The tape will clean between the teeth. It is smooth and covered with fluoride. Fluoride will strengthen the enamel and combat dental decay that is developing between the teeth. It also tastes good!

2. Oral B electric tooth brush

We love electric toothbrushes! Look out for the following qualities: rotating, pulsating, round headed. All basic oral B brushes will have these qualities. We can guarantee that your teeth will feel cleaner immediately!

3. Black is white whitening toothpaste

Those of you who know us, know that w are avid coffee lovers – hence the Nespresso machine at our practice. This toothpaste consists of coal particles that absorb the staining without damaging the enamel. The only downside is that it is black and can look a bit messy in the bathroom! Definitely works though!

4. Fluoride toothpaste (not whitening)

Any toothpaste that contains fluoride is good as it will strengthen the enamel.

5. Dentibrushes

These can be described as rubbery tooth-picks. It can take a few attempts before you get the technique right with these ones, and they do tend to bend in the beginning. They are easy and quick once you get used to them. They are also perfect for cleaning underneath fixed retainers.

6. Fluoriguard mouthwash

Fluoride strengthens the enamel and prevents dental decay. Use mouthwash twice a day after brushing. Make sure that you do not eat/drink/rinse for one hour following use. It tastes good and is not too strong.
