Demineralisation and Remineralisation Affect the Whiteness of your Teeth

Perhaps you have noticed some people have whiter teeth than others, and while this is partially genetic it’s also due to the thickness of the tooth enamel. A thicker layer of tooth enamel will prevent more of the natural colour of the tooth from shining through. The natural shade of your teeth is contained in the dentine layer just underneath the enamel. Younger people are more likely to have a thicker layer of enamel, and this not only gives them whiter teeth, but also helps prevent damage to the dentine. Anyone who is interested in teeth whitening in London may also be interested in how they can help lessen damage to the tooth enamel. So exactly why does tooth enamel become thinner, and what can be done to at least help lessen this effect?

Demineralisation Damages Tooth Enamel

Demineralisation is something that takes place every day, as it occurs every time we eat or drink something, especially foods containing carbohydrates and sugars. This is because they are the perfect food for plaque bacteria that are present in everyone’s mouth. As the plaque bacteria feed they create acid, which in turn will attack the tooth enamel. The result of this attack is that essential minerals including calcium and phosphate are removed from the tooth enamel, meaning the enamel becomes softer, thinner and more vulnerable to damage and decay. The acidity levels in the mouth increase just 5 minutes or so after eating, and remain higher than normal for between half an hour to an hour. After this time has passed the acidity levels begin to drop, and pH levels begin to return to something approaching normal. At this point a process called re-mineralisation can occur.

Remineralisation Helps Harden Tooth Enamel

This process results in some of the lost minerals being redeposited into the tooth enamel which has the effect of hardening the enamel once more. The reason for this is that some of the ions of the minerals that have been leached out of the enamel remain in the saliva.

Avoid Cleaning Your Teeth Straight after Eating

This re-mineralisation process is the reason it is better to wait a while after eating before brushing your teeth, as otherwise you may brush away some of these essential minerals forever. Waiting until they are redeposited will help strengthen the tooth enamel, after which you can safely brush your teeth.

Protecting Your Tooth Enamel

Taking measures to protect your tooth enamel will help ensure it remains stronger and thicker for longer, and simple measures include using fluoride toothpaste as some of the fluoride ions will remain in the saliva helping to protect and harden your tooth enamel. Ensuring you go to bed with clean teeth that have been properly flossed will help lessen the chances of you suffering from tooth decay and sensitivity that can result as the tooth enamel becomes thinner. Obviously this will lessen the chances of you needing fillings.

Healthy Teeth without Fillings are Easier to Whiten Effectively

Teeth that have been filled are less easy to whiten effectively, as composite fillings will stain within a few years, while porcelain inlays and onlays will remain unaffected by tooth whitening in London, and may not match newly bleached teeth Having less sensitive teeth would also make it easier to undergo teeth whitening in London, even though Dr. Chan’s method of whitening is especially formulated to reduce sensitivity.

Eventually most people’s tooth enamel will thin with age, and unless you are lucky enough to be blessed with exceptionally white dentin your teeth will look darker. Luckily this is where teeth whitening in London can really help, especially when performed by an expert such as Dr Wyman Chan on a healthy, well-maintaned mouth.
