Most dental disease causes no pain at all until it is well advanced. Although it is perfectly possible that the reason you have no pain is that you are completely healthy, it is equally possible that you have significant tooth decay, or advanced gum disease, or a chronic abscess, but do not know it. Our healthy mouth assessments are designed to pick up all types of potential problems, including checking for mouth cancer. If your teeth are healthy we can advise you on how to keep them that way. If you do not visit the practice in over 2 years, you are at risk of losing your place.
