A chipped tooth usually looks like a small, missing piece along the biting edge or corner of a tooth, leaving behind a rough or jagged surface you can feel with your tongue. Some chips are obvious at a glance, while others are so small you might only notice them by touch. What the chip looks like depends on how deep the damage goes, and that depth also determines whether you need treatment.
Minor Chips: Enamel Only
The most common type of chip affects only the enamel, the hard white outer shell of your tooth. These chips typically appear as a small notch or divot along the edge of a front tooth or the pointed tip (cusp) of a back tooth. The chipped area often looks slightly whiter or more translucent than the surrounding tooth because you’re seeing a fresh, unexposed layer of enamel. The edge feels rough or sharp when you run your tongue across it.
With enamel-only chips, the tooth color stays the same and there’s usually no pain at all. In fact, the only sign may be that missing fragment and the uneven edge it leaves behind. A dentist can often fix these by simply buffing and smoothing the jagged edge so the tooth blends in with the others. If the chip is on a visible front tooth, bonding (a tooth-colored resin) can rebuild the missing piece.
Deeper Chips That Expose Dentin
When a chip goes past the enamel and into the dentin, the layer underneath, the appearance changes noticeably. Dentin is naturally yellowish, so you may see a distinct yellow or brownish spot in the center of the chipped area surrounded by the whiter enamel border. The texture also differs: dentin is softer than enamel, so the exposed surface can feel slightly chalky rather than glassy smooth.
This is the depth where symptoms start. You’ll likely feel sensitivity to hot, cold, or sweet foods because dentin contains microscopic tubes that connect to the tooth’s nerve. The tooth may ache when you bite down on it. Visually, this kind of chip is harder to miss. The contrast between the yellow dentin and white enamel makes the damage stand out, especially on front teeth.
Severe Chips That Reach the Pulp
The most serious chips break through both the enamel and dentin to expose the pulp, the soft tissue inside the tooth that contains nerves and blood vessels. When pulp is exposed, you may see a pink or reddish spot at the center of the break. This color comes from the highly vascular tissue now visible through the opening. In some cases, the tooth actively bleeds from the chip site.
A pulp-exposed chip hurts significantly, often with a sharp, throbbing pain that doesn’t go away on its own. The tooth may also darken over the following days as blood from damaged pulp tissue seeps into the dentin, turning the tooth grayish or brownish. This type of chip needs prompt dental care to prevent infection.
Craze Lines vs. Actual Chips
Many people confuse craze lines with chips or cracks. Craze lines are tiny vertical lines visible on the surface of nearly every adult tooth. They’re microfractures contained entirely within the enamel that don’t penetrate into the deeper layers. You can often see them when light hits your front teeth at certain angles, appearing as faint hairline streaks.
The key difference: craze lines are flat. You can’t feel them with your tongue, and no piece of tooth is missing. They don’t cause sensitivity or pain. A true chip, by contrast, always involves a missing fragment or a rough edge you can detect by touch. If your concern is a line you can see but not feel, it’s almost certainly a craze line, which is cosmetic and harmless.
How Chips Differ From Cracks
A chip removes a visible piece of the tooth. A crack splits the tooth without necessarily losing any material. Cracks can be tricky because they sometimes look like a dark line running vertically down the tooth or across a back molar’s chewing surface. Some cracks become stained over time as bacteria migrate into the gap, making them appear as thin brown or gray lines.
One practical way dentists distinguish between chips and deeper cracks is by shining a bright light through the tooth. Light travels freely through intact enamel but stops at a fracture line. The portion of the tooth beyond the crack appears gray or dark while the rest glows. You won’t be able to replicate this test at home, but it explains why your dentist may hold a small light against your tooth during an exam.
A fractured cusp, where a pointed tip of a back molar breaks partially or completely, can look like a large chip but behaves more like a crack. The broken segment may still be attached, wobbling slightly when you chew. A fully split tooth, where the crack runs from the chewing surface all the way down through the root, separates into two distinct segments. This is rare and usually the end result of a smaller crack that grew over months or years.
What Happens if You Ignore a Chip
A tiny enamel chip that doesn’t bother you isn’t an emergency, but it’s worth getting smoothed out. The jagged edge can irritate your tongue or cheek, and the uneven surface traps more plaque than smooth enamel does.
Deeper chips carry real risk when left alone. Bacteria can enter the exposed dentin or pulp and work their way to the root tip, where they cause an abscess. Signs of an abscess include swelling in your face, cheek, or neck, sometimes severe enough to affect breathing or swallowing. You may notice a persistent, throbbing ache that radiates into your jaw, along with tender or swollen lymph nodes under your jawline. The tooth itself may darken as the nerve tissue inside dies.
A chip that looked like a small cosmetic issue can become a painful infection if the fracture extends deeper than it appears on the surface. Any chip that comes with sensitivity, color changes, or pain is worth having examined sooner rather than later.
Quick Visual Guide by Severity
- Small enamel chip: Tiny notch on the edge, white or translucent, rough to the tongue, no pain.
- Dentin-exposing chip: Visible yellow or brown spot within the break, sensitivity to temperature, noticeable gap in the tooth’s shape.
- Pulp-exposing chip: Pink or red spot at the center of the break, possible bleeding, intense pain, tooth may darken over days.
- Craze line (not a chip): Faint vertical line on the surface, completely smooth to the touch, no missing tooth structure, no symptoms.
