Some chips are minor and others are not
A small chip may only affect appearance, but a larger fracture can leave the tooth sensitive, sharp, or structurally weak. The amount of pain is not always a reliable guide to how deep the damage goes.
If the tooth feels rough, sensitive, or painful to bite on, it is worth getting it checked rather than assuming it is only cosmetic.
What treatment may depend on
Depending on the size and location of the chip, treatment may involve smoothing, bonding, a filling, a crown, or further evaluation if the crack runs deeper than expected. The goal is not just to improve the look of the tooth, but to protect it from worsening.
When to call sooner
Call promptly if the tooth is painful, the edge is sharp enough to cut tissue, the tooth broke after trauma, or you suspect a larger fracture rather than a small surface chip.
