No doubt! Yes, your tooth can be fixed! The only question is what the "fixing" will entail. If it is just a small chip with minor decay, bonding with an aesthetic resin is all that is required. If the fracture is more extensive, then a veneer or full coverage crown may needed. If the decay is deep enough (the lack of pain is not diagnostic), then a root canal, post and build-up, and crown may be in order. Only, an exam and x-rays from your dentist can determine the extent of the problem and the solution. Do not wait as the problem will only worsen. The old adage that "an ounce of prevention is worth a pound of cure" applies to most things dental. Good luck!
