Harley Street dentist Dr Richard Marques: top seven signs that you might have tooth decay 

  1. Sensitivity to hot and cold is an early indicator of a problem. It is fairly normal to be sensitive to cold, but if you experience pain with hot food or drink, it could be a warning sign of exposed nerves and early decay;
  2. A build-up of plaque on the surface of teeth can lead to visible cracks and holes where the enamel has worn away. Help prevent this by brushing twice a day, flossing regularly and rinsing with mouthwash. If the problem persists, see your dentist who will probably arrange a simple filling;
  3. If you start to experience sudden, sharp pains in your tooth or prolonged toothache, this could mean that one or multiple teeth have started to decay and need urgent treatment.
  4. Spots on the teeth, typically close to the gum line are one of the first signs of decay. They can range from white to black in colour and, if still visible after brushing, could indicate that your enamel has been affected;
  5. If biting or chewing causes discomfort or pain, it is very likely that tooth decay has spread. Be careful to avoid sugar altogether, as the acids in this will cause the decay to worsen much faster;
  6. When decay causes holes in the teeth, the gums will try to regenerate and grow into the space. The ‘new’ gums will be very sensitive and likely bleed when you brush – a strong indicator of decay;
  7. Once the infection reaches the pulp (centre) of the tooth, it can cause the tissue and bones surrounding it to move, generating puss and causing the area, particularly the gums, to swell which can be very painful. If you notice swelling, visit your dentist asap!

Braces offer a very effective solution for straightening teeth. Dr Marques fits new, ‘invisible’ braces on Brigida Donnarumma, a financial consultant, blogger and model. These barely noticeable braces enable Brigida to get on with her life as normal.
