Toothache

Toothache or dental pain can be caused by anything from a cracked tooth to a filling falling out, a gum infection, an abscess or even a wisdom tooth coming through. The most common cause, however, is dental decay.

Often, the pain starts as increased sensitivity when eating certain foods, such as something sweet, very cold or very hot. This is a sign that the pulp inside the tooth, where the nerves are, has become irritated. If the decay is not corrected, this can progress to pain that is felt even when not eating.

OTC oral analgesics can help to relieve pain until the individual visits a dentist. Rinsing with warm salty water can also be effective, as can applying a topical OTC pain-relieving product containing a local anaesthetic, such as benzocaine (e.g. Orajel Dental Gel).

Sensitive teeth

If a spoonful of ice cream or a sip of hot tea makes a person wince, it is likely that they are suffering from sensitive teeth. Teeth are not normally sensitive, but when enamel is worn away or gums recede, the underlying layer of dentine can become exposed. When stimuli such as hot or cold food and drink comes into contact with the exposed nerve endings within teeth, the result is sharp, sudden pain.

Common causes of sensitive teeth include:

• Tooth decay
• A cracked, chipped or worn tooth
• Worn or cracked fillings
• Exposed tooth roots due to receding gums or gum disease.

Frequent consumption of acidic drinks, incorrect brushing technique and brushing with a very abrasive toothpaste or brush can lead to enamel loss. Sensitive teeth are treatable €“ decayed teeth can be filled, and worn or cracked fillings can be replaced. Sufferers can also opt to use a toothpaste specifically designed for sensitive teeth (e.g. Sensodyne and Colgate Sensitive). Using a mouthwash for sensitive teeth (e.g. Listerine Advanced Defence Sensitive, Oral-B Sensitive Mouthrinse or Sensodyne Gentle Mouthrinse) may also be effective.
