Sensitivity from teeth, which is a common occurrence, can range from occasional twinges to discomfort lasting several minutes or hours. It may also be an indication of an underlying dental problem so should not really be ignored.
Sensitivity may be more pronounced when drinking something cold or hot or from cold air breathed in and with acidic or sweet foods.
The visible part of the tooth is covered by enamel. It protects the more vulnerable and softer dentine which is underneath. If the dentine is uncovered and this is most likely where the gum meets the tooth then the tooth can become more sensitive than normal.
Sensitivity can arise from over brushing especially when using the toothbrush in a scrubbing side to side motion (toothbrush abrasion).
Tooth enamel loss from acid attack from consuming too many sugary fizzy drinks can also lead to sensitivity (acid erosion).
When gums naturally shrink away from the neck of the tooth this is called gum recession then sensitivity may be more pronounced.
A build up of plaque due to incorrect or poor oral hygiene along the neck of the tooth (gum disease) can lead to gum recession leading to sensitivity.
The habit of clenching and grinding of teeth (tooth grinding) can cause the loss of enamel leading to sensitivity.
Of course a broken filling or tooth with a crack running from the biting surface of the tooth to the root can lead to discomfort especially from cold foods and drink.
Sensitive teeth can be treated with the use of tooth desensitizing tooth pastes especially when used twice daily and or rubbed into sensitive areas and left to work especially overnight. The problem may take several days to weeks to resolve however don’t delay to see your dentist if in doubt.
If your attempts to treat the sensitivity fails your dentist can apply special desensitizing products from gels to rinses and varnishes to the sensitive areas which may need to be applied over several visits to build up a protective layer. You may even need a seal or a filling around the neck of the tooth to cover the exposed tooth. If all else fails the tooth may need to have a root filling.
The best way to prevent sensitivity is to make sure that you brush your teeth twice a day with a fluoride containing toothpaste using a medium textured brush moving it in small circles for at least two minutes. Try to change your brush at least once every three months or sooner and try to avoid sugary foods and fizzy drinks especially between main meal times.
Remember if in doubt always take professional advice from your dentist and always maintain regular visits to prevent any problems getting worse.
