A decayed tooth can last for a variety of lengths of time. The amount of time that a decayed tooth will last depends on a number of factors, including the extent of the decay, the health of the tooth, and the type of treatment received.
If a decayed tooth is left untreated, the decay can continue to spread and the tooth can eventually become infected, resulting in an abscess. This can cause the tooth to become loose or break off altogether.
If the decay is caught early, however, it can be treated with fillings and other forms of restorative dentistry. Depending on the extent of the decay, the tooth may last for many years with proper care.
If the decay is more advanced, the tooth may still be salvageable with a root canal and crown. This procedure will help to restore the tooth structure and protect the tooth from further decay. A root canal and crown can help a decayed tooth last for many years.
Finally, if the decay is more severe and the tooth cannot be saved, it may need to be removed and replaced with an implant. An implant can last for many years with proper care.
In general, a decayed tooth can last for a variety of lengths of time, depending on the extent of the decay and the type of treatment received. With proper care and regular dental checkups, a decayed tooth can last for many years.
