Yes, a deep filling can cause nerve damage if the decay extends very close or even into the “pulp” nerve chamber. This is why all dentists urge their patients to take care of their decay immediately. Often times patients will say “but it never hurt before I got this done since you did this filling I’m having pain “. But here’s the truth of the matter, just because you’re not feeling any pain, doesn’t mean that the bacteria in your mouth causing the decay aren’t continually working and “chomping” at you’re tooth structure. You don’t feel it because it’s all internal. But now when the dentist goes in and starts drilling away the decay, the nerve becomes jarred and starts reacting. Think of it as carpenters ants chewing away at the foundation of your home. Usually, unless it’s already too late, the homeowner doesn’t know the damage is happening until a repair is necessary and you touch the offending wall and down it comes.
