Why do root canals have to be redone?
There are many reasons, but the most common are missed anatomy during the original root canal process or re-infection from recurrent cavities or restorative work that has begun to deteriorate.
Can you do a re-root canal treatment after the crown has been placed?
Yes. We make a small access opening through the biting surface of the tooth that does not affect the structural integrity of the crown.
Why do you use the rubber dam?
The rubber dam isolates the tooth we are treating and prevents any instruments or fluids we use from reaching the back of your throat while we work. The rubber dam also prevents any saliva from entering the tooth while we are working, which can lead to issues with infection. Use of the rubber dam is the standard of care for endodontics and treatment cannot be performed without it.
What will happen during retreatment?
First, the dentist will discuss your treatment options. If you and your dentist choose retreatment, the dentist will reopen your tooth to gain access to the root canal filling material. In many cases, complex restorative materials—crown, post, and core material—must be disassembled and removed to permit access to the root canals.
After removing the canal filling, the dentist can clean the canals and carefully examine the inside of your tooth using magnification and illumination, searching for any additional canals or unusual anatomy that requires treatment.
After cleaning the canals, the dentist will fill and seal the canals and place a temporary filling in the tooth.
Will my tooth be sensitive after treatment?
It is not uncommon for a tooth to feel tender or even exhibit a dull ache (bruise sensation) over the next few days as your body undergoes the natural healing process. These symptoms are temporary (usually last less than one week) and usually respond well to over-the-counter medications. This is a normal response and is no cause for alarm.
Is retreatment the best choice for me?
Whenever possible, it is best to save your natural tooth. Retreated teeth can function well for years, even for a lifetime.
Advances in technology are constantly changing the way root canal treatment is performed, so your dentist may use new techniques that were not available when you had your first procedure. Your dentist may be able to resolve your problem with retreatment.
As with any dental or medical procedure, there are no guarantees. Your dentist will discuss your options and the chances of success before beginning retreatment.
Why does my tooth have to be extracted if it is cracked?
Once a tooth has cracked or broken, there is no way to glue or mend the 2 pieces back together so that the tooth can endure normal chewing forces again. Even with the strongest glues in tests, previously cracked teeth quickly crack open again and allow infection to continue its course. Hopefully one day a strong biologic glue will be developed that will allow teeth to function again and prevent extraction.
What are the benefits of root canal retreatment?
Root canal treatment is virtually painless — infection and decay below the surface of your tooth can be painful. Root canal retreatment is virtually painless. Plus, the recovery is much more comfortable than a tooth extraction.
Root canal retreatment gives lasting results — root canal retreatment restores the integrity of your tooth and can prevent an extraction.
Root canal treatment is cost effective — root canal retreatment is generally less expensive than replacing your tooth.
