Have you ever noticed small notches or "ditches" forming along your gum line and wondered where they came from? Many people assume these grooves are caused by brushing too hard, but the real culprit is often something entirely different—your bite alignment. This phenomenon, known as abfraction, occurs when excessive force from clenching, grinding, or an uneven bite causes stress on your teeth, leading to tiny fractures near the gum line.
While these notches might not seem like a major concern at first, they can lead to tooth sensitivity, structural weakening, and even further gum recession if left untreated. Unlike cavities, which result from decay, abfraction is a mechanical issue caused by the way your teeth meet and distribute pressure.
In this article, we'll explain exactly what abfraction lesions are, why they form, and what you can do to prevent them from worsening and protect your long-term dental health. At Tanglewood Dental Associates, we regularly diagnose and treat abfraction, helping patients maintain strong, healthy smiles for years to come. Early detection during routine dental checkups is key to preventing further damage and discomfort.
Have you ever noticed small grooves or "ditches" forming near your gum line and wondered what's causing them? Unlike cavities, which result from bacterial decay, abfraction is a mechanical issue. It occurs when excessive force from biting, chewing, clenching, or grinding causes stress that wears away the enamel near the gum line.
These lesions often appear as wedge-shaped notches, primarily on the outer surfaces of the teeth. While they may not always cause immediate pain, they can lead to sensitivity, structural weakening, and even gum recession over time.
Many patients confuse abfraction with other dental issues, such as:
While all three conditions can appear near the gum line, abfraction is specifically caused by bite forces and not external factors like diet or brushing habits.
Abfraction doesn't happen overnight—it develops gradually due to consistent mechanical stress on the teeth over time. The primary culprits? Malocclusion (a misaligned bite), clenching, and grinding (bruxism).
When teeth don't come together properly, certain teeth absorb more pressure than they should when biting or chewing. Over time, this force creates micro-fractures in the enamel near the gum line, leading to the notched appearance characteristic of abfraction.
Many people grind their teeth in their sleep or clench their jaw throughout the day—often without realizing it. This constant pressure can exacerbate enamel loss at stress points along the gum line.
"If your teeth aren't aligned properly and you clench or grind, the force isn't directed straight down the root—it's hitting the side of the tooth. That's what slowly creates those notches in the enamel," explains Dr. Korloo.
Abfraction is often painless in its early stages, which is why many people don't notice it until the notches deepen or sensitivity develops. Here's what to look for:
As abfraction progresses, it can lead to:
✔ Increased Tooth Sensitivity – When enamel is lost, the underlying dentin is exposed, leading to pain from temperature changes.
✔ Weakened Tooth Structure – If left untreated, abfraction lesions can increase the risk of fractures.
✔ Higher Risk of Cavities – Once enamel is compromised, decay can set in more easily.
At Tanglewood Dental Associates, we use a combination of visual examination, digital imaging, and bite analysis to accurately diagnose abfraction. During your routine checkup, our team will:
Early diagnosis typically leads to simpler, more conservative treatment options, which is why we emphasize regular dental checkups for our patients.
While abfraction itself isn't caused by decay, it still requires treatment to prevent further damage. The best approach depends on severity and underlying causes. At Tanglewood Dental Associates, we offer several effective treatment options:
If bruxism is contributing to abfraction, a custom night guard designed by our team at Tanglewood Dental Associates can help redistribute pressure and protect your enamel. These guards typically provide relief within the first few weeks of consistent use.
"If a patient grinds their teeth at night, wearing a custom-fitted night guard can significantly reduce the force that leads to enamel loss," Dr. Korloo advises.
For patients with severe malocclusion, treatments like Invisalign or traditional braces may be recommended to correct bite alignment and evenly distribute chewing forces. These treatments typically take 6-18 months, depending on the complexity of your case.
For cases where notching is significant, our dentists may use a tooth-colored resin to restore the enamel and prevent further wear. This procedure can usually be completed in a single visit and provides immediate protection.
If sensitivity is a concern, fluoride varnishes or special toothpaste can help strengthen the enamel and reduce discomfort. Many patients experience noticeable relief within 1-2 weeks of beginning fluoride treatments.
The best way to deal with abfraction? Prevent it from progressing in the first place.
If your bite is misaligned, don't wait until symptoms appear. A simple consultation with our orthodontic team can prevent unnecessary stress on certain teeth.
If you grind your teeth, wearing a night guard is a simple and effective way to reduce long-term damage.
While abfraction isn't caused by brushing, over-brushing can make it worse. Use a soft-bristled toothbrush and avoid excessive pressure.
Since stress is a major trigger for clenching and grinding, relaxation techniques like meditation or jaw exercises can help minimize these habits.
If you've noticed small notches along your gum line or experienced sudden sensitivity, you're not alone. Abfraction is a common but often overlooked dental issue that we regularly treat at Tanglewood Dental Associates. While it isn't caused by decay, it can weaken your teeth over time, leading to discomfort and potential complications if left untreated.
