Worn-Down Teeth? How Acid Reflux and Grinding Are Damaging Your Smile

What Causes Teeth to Wear Down?

Tooth wear is a common but often overlooked dental issue. It can be caused by acid erosion (often from acid reflux or GERD) or mechanical wear (usually due to teeth grinding, also known as bruxism). Over time, these forces weaken your enamel—the protective outer layer of your teeth—leading to a host of problems including sensitivity, cracks, and changes in your bite.

Acid Reflux and Tooth Erosion

If you suffer from acid reflux, your stomach acids can travel up the esophagus and into your mouth. This acid can dissolve the enamel, especially on the inner surfaces of your teeth. Common symptoms include:

  • Increased tooth sensitivity

  • Yellowing of teeth due to exposed dentin

  • Thinning or translucent edges

  • A burning sensation in your mouth or throat

Silent reflux (LPR) is even more dangerous because it may occur at night without noticeable symptoms, allowing damage to continue undetected.

Grinding and Clenching: The Silent Destroyers

Bruxism—involuntary grinding or clenching of teeth—often occurs at night and may be linked to stress, anxiety, or TMJ disorder. This repeated motion causes teeth to flatten, chip, or crack. Signs of grinding include:

  • Jaw pain or tightness

  • Headaches or earaches

  • Flattened or shortened teeth

  • Notches at the gumline

  • TMJ clicking or popping

Left untreated, teeth grinding can accelerate tooth wear, misalign your bite, and strain your jaw joints.

Why You Shouldn’t Ignore Worn-Down Teeth

Worn-down teeth aren’t just a cosmetic concern—they can impact your oral function and overall health. As enamel wears away:

  • Sensitivity increases

  • Your bite becomes unstable

  • Teeth become more prone to fractures

  • You may develop chronic TMJ pain or muscle tension

Once enamel is gone, it doesn’t grow back, so early diagnosis and treatment are essential.

Treatment Options for Worn-Down Teeth

A comprehensive approach is required to restore function and prevent further damage. Treatments may include:

1. Dental Restorations

  • Composite build-ups to re-establish your bite

  • Crowns for severely worn teeth

  • Bonding for chipped areas

2. Night Splints or Orthotic Appliances

A custom TMJ splint can protect your teeth while relieving stress on the jaw joint. These appliances help deprogram grinding patterns and support muscular balance.

3. Managing Acid Reflux

Work with your GP or gastroenterologist to control reflux. Dietary changes, medication, and avoiding late meals can make a big difference.

4. Botox for Jaw Clenching

TMJ Botox treatment can help reduce muscle tension and control involuntary clenching.

When to See a TMJ Specialist

If you’re experiencing tooth wear, pain, or jaw tension, it’s time to consult a TMJ specialist. A proper diagnosis will help you understand the root cause—whether it’s acid reflux, teeth grinding, or TMJ disorder—and guide your treatment.
