#2 tooth with deep cavity - why infected after filling?
Whenever a tooth is drilled to have a new filling placed or an old filling replaced, the tooth is subjected to trauma. Because a tooth is a live structure with nerve and blood supply the trauma to a tooth can show in forms of sensitivity after a filling. When this happens, the tooth is hypersensitive and letting you know that it is inflamed and this inflammation can result in death of the nerve or the tooth just getting over the inflammation and go back to normal. Based on what you have told me, you may have had an inflammation in the tooth and it has gotten better, I would not do any further treatment with the tooth unless it hurts you further down the road. I would also have x-rays taken of the entire tooth showing the root of the tooth over time to make sure there is not infection at the end of the root. (if a tooth dies, over time, the nerve and blood supply in the tooth rots causing an infection at the end of the root) This can be seen on x-rays and also if you become symptomatic meaning having a toothache in the tooth. For now no further treatment is suggested for the tooth if you are without symptoms. READ MORE
What are the most visible signs and symptoms of a gum disease?
Early signs of gum disease is bleeding when you floss or brush. If the bleeding does not go away after flossing regularly for a week after you notice bleeding, consult a dentist. READ MORE
Can cavities in one tooth affect other teeth as well?
If you were told you do not have decay in any other teeth around the tooth you had filled, then more than likely the sensitive is from the filling. If the sensitivity doesn't go away, you need to see your dentist. READ MORE
What could be the reason for my mouth dryness?
Have you had a change in medication? Or supplements? Some medication such as blood pressure medication, can cause dry mouth. Sometimes the dryness can be due to other medical conditions. You will have to visit your physician if that is the case. READ MORE
How should I maintain my gum health?
Flossing at least once a day is imperative. Once a week is too infrequent since food and plaque can get caught under the gums and cause gingivitis. Purchasing a Waterpik is also a great device or removing plaque between teeth if you do not like to floss. READ MORE
