Tooth sensitivity is characterised by discomfort which comes in the form of a sharp, dull, shooting, or aching sensation. This can be brough on from the tooth being touched, or by hot and cold foods.

What causes tooth sensitivity?

Tooth sensitivity has a handful of factors which can cause tooth sensitivity, some of the most common are:

  • Teeth grinding, also known as bruxism.
  • Gum disease, as the gum lines pulls back leaving more of the tooth exposed.
  • Temporary sensitivity after treatments such as cleanings or teeth whitening.
  • Brushing aggressively.
  • Eating acidic foods.
  • Failed treatments of whitening or cleaning.
  • A cavity.
  • Cracked or broken teeth.

How to prevent sensitive teeth?

The simplest way to prevent getting sensitive teeth, is to attend your routine appointments every six to twelve months with your dentist. Your dentist is equipped to spot problems in the mouth, making them the perfect preventative solution.

Other ways which you can prevent tooth sensitivity is to brush the teeth gently, using a fluoride toothpaste. There are soft bristled brushes which can help limit the risk of gum loss and the enamel being worn down.

Ensure you are brushing twice a day for no less than two minute and aim to floss at least once a day to ensure all food is removed from between the teeth. Do not rinse your mouth after brushing your teeth as this will wash away the fluoride which is ultimately helping your tooths enamel.

Adjusting your diet to avoid eating foods and drinks which are acidic or sugary will also help decrease the chances of sensitivity. Lifestyle changes include, reducing alcohol intake as well as quitting smoking or vaping.

How to treat sensitive teeth?

Sensitive teeth are best treated with everyday maintenance, ensuring to floss and brush.  Here are the treatments given to those with sensitive teeth:

  • Using a toothpaste made for sensitivity.
  • Gels, varnishes, and rinses containing fluoride, which can gradually form a protective layer over the teeth.
  • Fillings for those with cavities or cracked teeth.
  • Replacing your toothbrush every 2-3 months.

Symptoms of sensitive teeth?

Sensitive teeth are easy to notice as there is some form of discomfort in the area, this can be a dull ache or pain that continues for a while after initially being triggered.

It may hurt when eating foods that are hot or cold, and sweet and sour foods can also cause the sensitive tooth to start hurting. Some may not be affected by seasonings or heat but may still be in pain due to the pressure of eating or touching the area.
