Diet Advice

What we eat affects our bodies in numerous ways. Your diet also affects your teeth. We are always told about the things that are bad for our teeth but it seems that everything is bad for us one way or another. The aim of this advice sheet is to reinforce the foods that are bad for your teeth and also give you some idea of a diet that is generally healthy, but particularly good for your teeth!

What not to eat

We should all know some of the things that are bad for our teeth. Here is a quick list of the most obvious:

What about the less obvious things?


The reason that fizzy drinks are bad for your teeth is because they are high in acid ingredients, just read the side of a can of cola to see! This means that diet drinks are no better for your teeth than normal varieties, because they still contain the same acid.

You can still get caught out if you avoid fizzy drinks. Squashes and fruit juices contain natural acids, although at lower levels than fizzy drinks. Flavoured and carbonated waters contain acids as well.

Foods can contain acids as well. Most obvious are citrus fruits like oranges but also in green apples. The tart flavour comes from citric acid which can attack your teeth as much as any can of pop!!


Sweets are the most obvious source of sugar however any intake can help to cause decay. Particular caution needs to be taken to find foods that contain hidden sugars. Baked beans, ketchup and diet foods are all examples of foods that contain significantly higher sugar concentrations than you would expect.

So what can I eat?

The foods above are bad for your teeth. Some foods are neutral. The following diet suggestion contains some neutral foods but also some foods that actually help fight tooth decay as well as look after your general health:






“Invisalign – Light. Crooked front teeth that had started to become more noticeable. This, in turn, started to affect my confidence.

The experience at Beaufort Park was excellent throughout. The staff, from the initial consultation, were friendly and professional. The welcoming reception staff through to the excellent dentist (Russell Gidney) have made this an (almost!) pleasurable experience!

I feel so much more confident and happy to smile again in public.

“I hated my smile in photos, I looked as though I only had about 4 teeth! 🙁

Treatments have all been explained, the team have been great & I have started to notice my teeth changing & looking good – despite not even being half way through my treatment (Invisalign Aligner 11/23). I am so happy with the progress.

Thank you! 🙂

Super, I would recommend to anyone considering treatment.

“After years of being unhappy with my crooked teeth and avoiding photographers if at all possible.

I decided to seek corrective treatment at the grand old age of 55 in order to be able to smile at my daughters up coming wedding. After a chat with the Beaufort Dental practice I decided on a course of CFast treatment. In a few short months I was thrilled with the result. Straight teeth which were so much easier to care for and which looked 100 per cent more attractive

The cost was manageable too and I paid at intervals during the treatment. I wish I’d done it years ago.


“I did not like my teeth so didn’t smile.

Invisalign – absolutely brilliant! Very professional team, extremely happy with the results!”

“Even though my oral hygiene has always been excellent I have for many years hated my teeth which were discoloured + the crowns rather mismatched.

Dr Russell Gidney was the first dentist I had confidence in to correct my problems. He showed great empathy, kindness + professional skill. He made me feel completely at ease.

His dental nurses + admin staff are all lovely. The outcome is better than I expected, I now have a lovely smile!”

Pamela C

“I recently had cosmetic work on my teeth carried out by Russell at the surgery. he explained everything in detail and I am overjoyed with the results. The difference it has made is amazing and I thoroughly recommend them. The staff are very helpful too!”
