Frequently Asked Questions About Dental Health
FAQs
Our FAQs are the most commonly-asked questions put to our Dental Helpline over the last year. If you have a question for us, you can ask our Dental Helpline by telephone or email. Alternatively, please take a look at our library of oral health information, which contains a wide range of oral health advice in an easy-to-understand Q&A format.
Thinking hard about something other than the treatment is a good distraction. Try to solve a puzzle in your mind, or perhaps work out a plan for each day of next year’s holiday. Or give yourself something tricky to do – try to wiggle each toe in turn, without moving any of the others.
The usual method for fitting a crown involves shaping the tooth under local anaesthetic and then taking an impression using a rubber-like material. The impression is then sent to the laboratory along with the details of the shade to be used, and the technician makes the crown.
Dental decay happens when the enamel and dentine of a tooth become softened by acid attack after you have eaten or drunk anything containing sugars. Over time, the acid makes a cavity (hole) in the tooth. ‘Dental decay’ is the same as tooth decay and is also known as ‘dental caries’.
Erosion usually shows up as hollows in the teeth and a general wearing away of the tooth surface and biting edges. This can expose the dentine underneath, which is a darker, yellower colour than the enamel. Because the dentine is sensitive, your teeth can also be more sensitive to heat and cold, or acidic foods and drinks.
