A hairline crack in tooth enamel might seem minor initially, but if left untreated, it can lead to sensitivity, discomfort, and long-term damage. These micro-cracks are often difficult to detect without a dental exam, and the symptoms may come and go, making them easy to ignore.
In this article, we’ll explain what causes these tiny fractures, how to spot them, and, most importantly, the treatment options that actually work to protect your tooth and prevent future complications.
What Causes Hairline Cracks in Teeth?
Hairline cracks can form from everyday habits or repeated stress. These minor fractures may go unnoticed until symptoms appear.
Common causes include the following:
- Teeth grinding (bruxism): Frequent clenching or grinding (especially at night) puts pressure on teeth, increasing crack risk.
- Chewing hard foods: Ice, nuts, or hard candy can stress enamel and create microcracks.
- Temperature extremes: Rapid shifts from hot to cold can cause enamel to expand and contract, leading to fractures.
- Dental injuries: Sports accidents, falls, or biting hard objects may result in cracks.
- Wear and tear: Repeated stress naturally creates surface cracks in the enamel over time.
What are your treatment options?
The proper treatment for a hairline crack in tooth enamel depends on how deep the crack is and whether it’s causing pain or affecting function. Here are proven options Dr. Bryce Richardson may recommend:
- Polishing or smoothing: If the crack is shallow and limited to the surface, Dr. Richardson may gently polish the area to reduce irritation and smooth rough edges.
- Veneers: For small cracks, Dr. Richardson can place prepped or no-perp veneer. These are slim “covers” that go over your tooth to hide the crack and prevent further damage to your teeth.
- Dental crown: When a deeper crack is present, we may recommend a crown covering the tooth entirely, restoring strength and function.
- Night guard: If you grind your teeth, Dr. Richardson suggests wearing a custom night guard while sleeping to prevent further stress on your teeth.
- Root canal therapy: If the crack extends into the pulp, Dr. Richardson may recommend a root canal treatment to remove infection and help save the natural tooth.
- Tooth extraction: In more severe cases where the crack runs below the gumline, extraction may be necessary. Dr. Richardson can then guide you through replacement options like implants or bridges.
When to Schedule a visit
You should schedule a dental visit if you’re experiencing:
- Sharp pain when chewing or biting, especially if it comes and goes
- Sensitivity to hot, cold, or sweet foods that lingers longer than usual
- Discomfort that’s hard to pinpoint but feels like it’s coming from a specific tooth
- Visible lines or rough spots on the enamel, even if they don’t hurt
- Gum swelling or pain around one tooth, which may suggest a deeper crack
