Sensitive Teeth

Do you feel a shooting pain in your teeth when eating or drinking something hot? Does the thought of biting into an ice cream or a cold, hard apple make you wince? Sensitive teeth can be a burden for many people and can be caused by a variety of factors. It is always important to seek advice from a dental professional so that the source of the problem can be identified and treated.

There are several causes of sensitivity:

  1. Temporary pain can be experienced after tooth whitening procedures and is treated with over-the-counter painkillers.
  2. Dental erosion, or the loss of tooth enamel, can also cause sensitivity. Enamel is the hard outer coating of a tooth that protects the sensitive dentine underneath. If enamel is worn away or eroded, this dentine is exposed which can lead to pain and sensitivity, which can be worsened with extreme temperatures.
  3. Erosion can be caused by your diet (frequent consumption of high sugar or high acid food or drink), tooth brushing habits (brushing too hard), tooth grinding, certain medical conditions and eating disorders.

For top tips on protecting your enamel and for effective treatment of tooth sensitivity, come to the practice for a check-up and we will create an individualised care plan for you.

Benefits to not having sensitive teeth

Tooth sensitivity (also known as dentine hypersensitivity) often appears as a painful reaction to temperature changes, pressure, sweet and acidic food or drink. This reaction may be mild and tingling, or sharp and intense. People whose teeth are sensitive often feel pain when they eat or drink things which are very cold. The classic example is eating ice cream, but simply being out in the cold weather is sometimes enough to set off the problem. Sensitivity to touch may also mean that tooth brushing is uncomfortable.

Research shows that 1 in 3 people in the UK suffer from sensitive teeth at any one time. Dentine hypersensitivity can occur from 15 to 70 years of age or more, however the age group when it occurs most is between 20 and 40 years.

Triggers of tooth sensitivity and the severity will vary from person to person, although the most common are:

  • Cold food and drinks (e.g., ice cream)
  • Over-enthusiastic or incorrect tooth brushing
  • Hot food and drinks (e.g., hot tea or coffee)
  • Sharp acidic foods (e.g., apples, oranges)

Any teeth can be affected but the most likely are those at the front corners of the mouth. It is suggested that this might be because these are the teeth which tend to be brushed more vigorously causing the wearing away of protective tooth enamel.

A healthy tooth has a chamber inside it for the tooth pulp, which consists of nerves and blood vessels. A young and healthy tooth has a large pulp chamber where the sensitive nerves are more exposed to temperature or pressure changes from the outside. However, tooth sensitivity can occur at any age. There are two general ways in which this sensitivity can develop:

Wearing or destruction of the hard, protective outer layer of the tooth crown called enamel. This may be related to:

  1. Biting abnormalities or abnormal tooth grinding.
  2. Toothbrush abrasion i.e., the wearing-away of enamel and/or recession of gums caused by over-enthusiastic or incorrect brushing.
  3. Dietary erosion - the destruction of enamel by acidic food and drink or by acid regurgitation from the stomach.
  4. Habit - nail biting or the placing of metal objects between the teeth.
  5. Attrition - the wearing away of enamel by tooth grinding.

Gum recession exposing the softer, porous tooth structures called dentine and cementum. This may be related to:

  1. Chronic gum (periodontal) disease
  2. Surgery - difficult tooth extractions
  3. Incorrect tooth brushing

Sensitivity and dental pain can also be experienced for a number of other reasons:

  • Chipped teeth
  • Fractured or cracked fillings
  • Dental decay (caries)
  • Deep fillings
  • Cracked teeth

Avoidance of this condition is possible if the teeth are cleaned thoroughly but carefully twice a day. Chewing a disclosing tablet (obtainable from the practice or local chemist) after brushing will show if any plaque is left behind. Using the correct brushing technique is essential and use of a specialist toothpaste formulated for sensitive teeth. If you need advice as to the best technique to use, ask a dentist or hygienist.

Care should be taken with diet: a high intake of acid-containing food and drink such as citrus fruits and fizzy drinks will make teeth more sensitive and can lead to destruction of the tooth enamel.

A dental professional can help by:

  • Applying fluoride varnish to exposed sensitive dentine or cementum.
  • Applying a sealer to exposed root surfaces to block the tiny tubes which are exposed or offer treatment that will desensitise the dental nerves (no drilling is required).
  • Correcting any bite abnormalities to help reduce the wearing of enamel.
  • Placing fillings to cover exposed dentine or cementum on root surfaces.
