Goodbye cavities and tooth decay

Do you have holes in your teeth that are getting worse? Never delay a dental filling as it can save you so much money on future dental work. Prevention is key.

White, natural dental fillings available


  1. Any pain or sensitivity when eating, drinking or biting down?
  2. Do your teeth feel sore when pressing or running your tongue across them? Unexplainable bad breath?
  3. Can you feel or see visible holes in the teeth? Or is there visible brown or black staining?

You likely have a cavity. Do not ignore it – clear decay and fill your cavity (we have appointments available today). 

*Patients can combine their dental filling appointment with an exam for £280 (including a hygiene visit). Book here.

You might need a dental crown instead

Depending on the extent of your decay, our dentist might recommend a dental crown to repair your decay and further protect your tooth. 

Dental fillings are perfect in minor decay cases, where minimal damage to the tooth has been caused. If you’ve ignored decay for some time, and most of the tooth has cracked away, you might need a dental crown.

When decay is rampant and ignored for prolonged periods, dental decay might have taken over a significant portion of your tooth, and a regular dental filling is unlikely to be your recommended next step.

Dental crowns cost £1,200.

“I can’t recommend the Perfect Smile enough. The staff are very friendly and professional, and the service I received was excellent. Sam and Sophie thoroughly explained every step of my treatment and made the whole experience a very positive one.”

Leave it to the dentist - start with a check-up

We don’t expect you to have all the answers and know if you’ll need a dental filling. Dental pain is a common symptom of many dental problems, so our dentists will need to assess your oral health to identify what’s really going on.

Our check-ups cost £65 for existing patients and from £100 for new patients. Book now.

I couldn’t recommend the Perfect Smile studio enough. When I first discovered them I used to drive all the way from the Lake District to see them they’re that good!!! Always friendly & so helpful with rearranging appointments etc. & I always love my chats with Shivani the hygienist she’s such a ray of sunshine. My teeth are so important to me which is why I only now see the best of the best. Thanks everyone see you again soon!

Sagar Shah was my dental professional for my composite bonding. He is the best I could have hoped for and more! He took such good care of me and always making sure I felt comfortable, respected my opinions and decision making so that the whole experience was a shared one, felt almost like teamwork. I felt completely safe in his hands and I looked forward to our appointments as he put me completely at ease- not a lot of people can say they looked forward to a dentist appointment! The dental nurses were some of the nicest humans I’ve met and really added to the experience. I was genuinely sad when it was over in a way! I would 10/10 recommend to anyone considering them.

Had a hygienist appointment with Shivani. I had always been happy with my previous hygienist but the treatment was much more comfortable with Shivani and achieved a better result. I didn’t experience any discomfort during the treatment and she is a really nice lady who also gave me lots of aftercare advice. Would definitely recommend.
