Cavities are holes that develop in the tooth surface. They are caused by tooth decay, one of the most common preventable illnesses among children and adults in the UK. If you have cavities or tooth pain, we urge you to get in touch with your dentist and make an appointment. Leaving cavities increases the risk of severe infection and may even lead to tooth loss.

What causes tooth decay?

Tooth decay is caused by harmful bacteria that collect and multiply in the mouth. These bacteria release acids that attack and erode the tooth enamel, eventually wearing holes in the outer layer of the tooth. The most common risk factors for cavities are poor oral hygiene and a diet that contains a lot of sugary and acidic foods.

How can I tell if I have a cavity?

Sometimes it’s possible to feel or see a cavity. You may be able to see the hole in the surface of the tooth, especially if it has become discoloured. You might also feel it when you run your tongue over the surface of the tooth. Other signs of decay include increased sensitivity that manifests itself through pain when the teeth come into contact with hot and cold substances, toothache and a feeling of weakness when you use the tooth.

Why it’s important to treat cavities

If you have cavities, it’s important to get them sorted by your dentist. Once the enamel layer of the tooth has been penetrated, there is a risk of infection spreading through the tooth into the living tissue of the tooth, known as the pulp. It is possible for the pulp to become infected and this may result in severe damage or even loss of the tooth. In this case, it may be possible to save the tooth by means of performing root canal treatment. Decay can also increase the risk of dental abscesses, which are usually very painful.

As with all dental diseases, we believe that prevention is better than cure when it comes to tooth decay and we recommend a good daily oral hygiene routine, regular dental check-ups and steering clear of too many sugary treats!
