Why see a specialist orthodontist?

A specialist orthodontist is a dentist who has completed several years of extra full-time training in orthodontics and is listed on the General Dental Council's Specialist List. That training covers how teeth, jaws and bite work together – not just how straight the front teeth look – so your treatment is planned around a healthy, stable result.

How treatment works

  1. Consultation
    We look at your teeth and bite, talk about what you'd like to change and explain your options.
  2. Records & plan
    We take photos and a scan or impressions of your teeth and plan your tooth movements, then talk you through the plan.
  3. Treatment
    Wear your aligners or have your braces fitted, with regular check-ins with our orthodontic team.
  4. Retainers
    When your teeth are in place, retainers keep them there. We'll show you how to look after them.

Orthodontist Waterloo: common questions

Do I need a referral to see an orthodontist?

No. You can book a consultation with us directly. Clear aligner consultations are free, with a £10 refundable booking deposit.

How much do braces or Invisalign cost in London?

At our Waterloo practice, AddaSmile aligners start from £1,499, Invisalign from £1,850 and fixed braces from £1,000. Your exact price depends on your case, and we give you a written quote before treatment starts.

What's the difference between Invisalign and AddaSmile?

Both are clear, removable aligners. Invisalign is a well-known brand that suits a wide range of cases. AddaSmile is a clear aligner brand that offers a more affordable option for many mild to moderate cases. We'll recommend what suits your teeth at your consultation.

How long does orthodontic treatment take?

Mild cases can take a few months, while more complex cases often take 12–24 months. We'll give you an estimate at your consultation.

Am I too old for braces or aligners?

No. Many of our patients are adults. As long as your teeth and gums are healthy, you can usually have orthodontic treatment at any age.

Is orthodontic treatment available on the NHS?

NHS orthodontic treatment is generally for under-18s who meet NHS eligibility criteria. Adults usually have private treatment. Ask us and we'll explain the options for you or your child.

Can I pay monthly?

Yes. You can spread the cost of treatment with 0% finance through Tabeo, subject to status.

Do I need to wear a retainer afterwards?

Yes. Teeth can move back over time, so retainers are an important part of treatment. We'll advise you on the right retainer and how long to wear it.

What if my brace breaks?

Contact us – we can usually repair a broken bracket or poking wire quickly. See our emergency dentist page.
