What is Orthodontics?

Orthodontics is a special branch of dentistry concerned with the prevention and cure of various irregularities of the jaws and teeth. Most orthodontic treatments make use of custom-made braces to cure these dental conditions. An expert who handles such cases and provides the necessary treatments is called an orthodontist. These experts have to master specific techniques and skill sets beyond the standard curriculum of dental training. Modern orthodontics caters to aspects of aesthetic appeal and practical functionality, teeth alignment and teeth straightening.


When would you need orthodontic treatments?

Orthodontic treatments become necessary if you have any of the following problems:

  • Crowded or badly spaced teeth.
  • Extra or missing teeth (A condition called hypodontia).
  • Irregularly positioned teeth or ectopic teeth.
  • Decay or chronic disease of the gums.
  • Abnormalities caused by thumb sucking.
  • Dental trauma.
  • Premature loss of baby teeth.

What are the benefits of orthodontic treatment?

  • Improved aesthetic appearance, a more beautiful smile with a boost to self-esteem.
  • Teeth straightening reduces the chances of cavities and gum disease.
  • Correcting teeth alignment improves bite.
  • Lessening the risk of accidental injury for protruding teeth.
  • Eliminating any excessive stress on the jaw.

With modern orthodontic dentistry offering so many options you will never be too old for some form of orthodontic treatment.

Ideally you should take your child for orthodontic treatments as soon as a you notice a problem. There’s no ideal age as such although some parents prefer to wait until children are over 7 years of age.

You will have a thorough examination by our expert, from which a comprehensive report will be prepared outlining your problems, the suggested treatment, detailed costing and easy payment plan options.

Different orthodontic treatments are accomplished in different lengths of time. Your treatment duration will be confirmed after you have undergone a thorough clinical examination. The average duration of a treatment, however, is between 12 to 18 months.


The Dentist, Hygienist, Dental Nurses & Especially the Receptionist staff are very Polite, Friendly & most importantly they try to fit you in quickly in the event of an emergency. Recently I couldn’t get the time of work for an emergency appointment for my 81 year old Mum so I called an Uber for her & told the receptionist this. The young Black Lady called me when she ordered & place my Mother in a cab – so she went above & beyond her duties with a lot of Customer Care & Respect for my Mother- Thank You so much

Vince A.

Great service! Im usually so nervous when coming in to the dentist but my dentist was so pleasant and polite ! Dulwich Dental Office will definitely be my dentist for life

Tomike O.

I lost my two front teeth whilst at school and had complications for years. Unfortunately I ended up needing an implant – which I had been avoiding! I wish I had done it sooner. Dr Patel was fantastic and guided me through each stage. He was always contactable to answer any queries or concerns. Very happy with the end result and would reccomend.

Tom O.

Registered and seen on the NHS within 2 weeks – amazing. Really friendly staff, would definitely recommend

Tom C.

I have recently finished an invisalign program with Pooja at dulwich dental office and couldn’t be happier. The treatment was easy and pain free and the results are great. Pooja’s experience and friendliness made me feel at ease throughout. I would 100% recommend for anyone considering similar treatment.

Toby B.

A great surgery; Dr Cavan in particular spent time with me to make sure my new night guards fitted well and were up to the job

Dentist Pooja Pillay is excellent and was very patient with me as I I took a long time (years!) deciding whether or not to take the plunge and have Invisalign to straighten my teeth. It didn’t take too long and was easier than I thought it would be. Pooja kept a close eye on how it was all progressing and we even went a bit longer with it just to really perfect the result. I’m delighted with the outcome. Everything was included in the price, even the extra aligners and appointments when we decided to go on a bit longer. All staff at the practice have been excellent. Highly recommend.

Susie F.

I had my Invisaligns done by Dr Pillay and she really took the time to make sure my teeth are lovely and straight. She has always been available with any queries or follow up treatment I needed – and made me feel well looked after from the beginning and end of the treatment. I really recommend seeing her if you want to get Invisaligns done.

Stella C.

Dr. Cavan is super attentive and thoughtful and great at putting is patients at ease. I hate going to the dentist but havent dreaded it once. Everyone is super friendly and clinic is nice. I could not recommend more.

I am undergoing a course of Invisalign treatment with Dulwich Dental Office and I am so pleased with the results, even at this early stage. It is great that I can take the braces out to eat and clean my teeth. I am looking forward to the end result.
