Tooth wear occurs through four processes: attrition, abrasion, erosion, and abfraction. Bruxism is the most destructive of these, grinding down occlusal surfaces and reducing tooth height year by year without the patient realising it is happening. Acid erosion from GERD or dietary acids makes things worse when it runs alongside grinding. When wear spreads across multiple teeth and the occlusal vertical dimension is affected, full mouth rehabilitation becomes the only workable treatment path. A prosthodontist identifies the underlying cause before any restoration plan is confirmed.
Dr. Namratha Chandrahari, a renowned dentist at Dental Clinic in Banjara Hills, patients with worn-down teeth often present years after the damage began, because the process is slow enough that most people do not notice it until function and aesthetics are both affected.
What Are the Most Common Causes of Worn-Down Teeth?
Rarely just one thing. Most severe presentations involve two or three causes compounding each other.
Bruxism: Grinding and clenching during sleep flattens occlusal surfaces faster than almost anything else. Most patients do not know they are doing it until a dentist identifies it.
Acid erosion: GERD is the most consistent chemical threat because gastric acid reaches the mouth below the 5.5 pH threshold at which enamel dissolves. Citrus and fizzy drinks cause the same erosion, at a slower rate.
Abrasion: Hard-bristle brushing or abrasive toothpaste removes enamel mechanically. It shows up as notching at the gum line, not flattening at the biting surface.
Abfraction: A misaligned bite creates repeated occlusal stress at the cervical area, producing wedge-shaped defects that do not follow typical wear patterns and often go undiagnosed.
Identifying the cause matters before treatment begins. Rehabilitation on a patient still grinding without a night guard or still refluxing without management will not hold long-term. Learn more about full mouth rehabilitation.
When Does Tooth Wear Require Full Mouth Rehabilitation?
Some wear is manageable with single restorations. Some is not, and the difference matters before any treatment decision is made.
Generalised wear across most teeth: Single restorations cannot restore proper bite because the whole occlusion has shifted. Everything needs rebuilding together or nothing holds correctly.
Loss of vertical dimension: Teeth worn down enough to reduce face height change how the jaw closes and how muscles function. This cannot be corrected one tooth at a time.
Sensitivity that will not resolve: Exposed dentine causes persistent temperature and sweet sensitivity. When the exposure is too widespread, topical treatments stop working and restorative coverage is the only option left.
Aesthetic and functional collapse together: Smile designing handles cosmetics alone, but when worn teeth affect both appearance and bite at the same time, a full rehabilitation plan sequences both together rather than treating them separately.
Before deciding between restoration types, understanding the difference between veneers and crowns helps narrow down which the DSD preview should be built around.
Why Choose Dr. Namratha Chandrahari?
Dr. Namratha Chandrahari holds MDS Prosthodontics and MFD RCSI qualifications and has completed over 500 full mouth rehabilitation procedures at Enamel Dental in Banjara Hills, Hyderabad, across cases involving bruxism-related wear, acid erosion, and combined presentations needing full occlusal reconstruction.
Treatment here starts with identifying what caused the wear, not just restoring what is left. A rehabilitation plan that skips cause assessment fails.

FAQ
What is the most common cause of worn-down teeth?
Bruxism. It grinds down occlusal surfaces through repetitive clenching, often undetected for years.
Can acid reflux damage teeth?
Yes. Gastric acid reaching the mouth dissolves enamel progressively, causing erosion across multiple teeth.
How do I know if I need full mouth rehabilitation?
Generalised wear across multiple teeth, reduced tooth height, persistent sensitivity, and changes to how your bite feels are the key indicators a prosthodontist looks for during assessment.
Can worn-down teeth be restored without full mouth rehabilitation?
Localised wear on one or two teeth can be treated individually. Once wear is generalised and affects vertical dimension, it cannot.
