Dentists are frequently asked questions about chipping a tooth—“Is it that big a deal? Doesn’t it depend on how big the chip is? I mean if it is just a little chip, it can’t be that bad…can it?” The answers to these questions are variations of the same theme.
Yes, chipping a tooth means you have lost valuable tooth structure and potentially laid the foundation for additional chips and cracks. Or you may need a root canal if the chip is close to the pulp containing the nerve and it doesn’t heal properly from the trauma.
As for repairing a chipped tooth, your dentist can usually fix minor chips with modern bonding techniques using tooth-colored filling materials.
For larger chips that involve more tooth structure, your dentist may suggest a crown (cap) or a veneer. The most important thing to remember is that if you chip a tooth, you need to see a dental professional for a proper evaluation and treatment remedy.
