A wedge or a groove
Sharp V-shaped wedges point towards stress or aggressive brushing; smooth, saucer-shaped grooves are more typical of acid erosion. Many notches show features of both.

Notches in Teeth at Gum Line: What Causes Them and When They Need Filling
Small notches where the tooth meets the gum are usually wear, not decay. Hard brushing, acid and heavy biting forces each play a part. Many can be monitored; some need a bonded filling.

Quick answer
What causes notches in teeth at the gum line?
Notches at the gum line are usually non-carious cervical lesions: loss of tooth structure that is not decay. They typically come from a mix of hard or scrubbing brushing, acid from food, drink or reflux softening the surface, and heavy biting or grinding that flexes the tooth near the gum, called abfraction. At Creative Arts in Dubai the cause is assessed first, then the notch is monitored or repaired with a bonded filling.

Symptoms
What do notches in teeth at gum line look and feel like?
You may notice them in the mirror, with your tongue or because a tooth has started to twinge.
A yellow band
Enamel is thinnest at the neck of the tooth. Once it wears through, the yellower dentine underneath shows as a band just above the gum.
Sharp sensitivity
Exposed dentine has tiny tubules running towards the nerve, so cold drinks, sweet food, air or the toothbrush can cause a short, sharp twinge.
Hard and shiny, not soft
Wear notches usually feel hard and look clean. A soft, brown or sticky area at the gum line is more likely decay and needs checking sooner.
Causes
Why do notches form near the gums: brushing too hard or grinding?
Usually it is not one cause but several working together on the weakest part of the tooth.
- Brushing wear (abrasion). Hard bristles, a scrubbing side-to-side action and very abrasive or whitening pastes slowly wear the neck of the tooth, especially once gum has receded and the softer root surface is exposed. Notches are often deeper on the side opposite your brushing hand. Our guide on how to brush your teeth shows a gentler technique.
- Acid erosion. Acid from soft drinks, juices, citrus, sports drinks, vinegar or reflux softens the surface for a while, so brushing straight afterwards removes more tooth. See our guides to acid reflux and tooth erosion and whether to brush right after eating.
- Biting stress (abfraction). One theory is that heavy biting, clenching or grinding makes the tooth flex slightly at the neck, causing tiny fractures in the enamel there. How much this contributes on its own is still debated, but grinding often goes with these notches, and treating it is sensible. Our page on teeth grinding explains the signs.
- Gum recession. Receding gums expose root surface that wears faster than enamel. Our page on receding gums covers why gums recede.
Is it wear or decay?
Notch, decay or receding gum: how do they differ?
All three happen at the gum line and can look similar. A dentist confirms which it is with a close examination and sometimes an X-ray.
| Wear notch | Decay at the gum line | Receding gum alone | |
|---|---|---|---|
| Surface | Hard, smooth, often shiny | Soft or sticky, may be chalky white or brown | Normal tooth surface, just more of it showing |
| Shape | Wedge or scooped groove | Irregular, often next to plaque | Tooth looks longer; no groove |
| Main cause | Brushing, acid, biting stress | Plaque bacteria and sugar | Gum disease, brushing, thin gums |
| Usual first step | Remove causes, desensitise, monitor | Treat the decay; a filling if a cavity has formed | Gum assessment and gentle cleaning |
Notches and recession often occur together. Our page on worn teeth covers wear on the biting edges and other surfaces.
Will they get worse?
Will notches at the gum line get worse over time?
They can, but slowly, and only while the causes continue. A notch is lost tooth: it does not grow back. Changing how you brush, cutting down acid contacts and protecting the teeth from grinding can slow or stop further loss. That is why the first visit focuses on the causes rather than the filling.
Left alone, a deep notch can trap plaque against the gum, become harder to clean, and in time come close to the nerve or weaken the neck of the tooth. Photographs or scans at check-ups let the dentist see whether a notch is changing, which helps decide whether it needs repair or can simply be watched.
Seek prompt dental assessment if…
a tooth with a notch starts to ache on its own, throbs, wakes you at night or hurts for a long time after cold; the notch looks soft, brown or is getting bigger quickly; a gum boil or swelling appears next to it; or the tooth feels loose or breaks. The clinic is open daily 10:00–20:00, with no overnight service. Facial swelling with fever, difficulty breathing or swallowing, swelling spreading to the eye or neck, uncontrolled bleeding or a head or face injury need a hospital emergency department straight away.
Treatment options
Do notches in teeth at gum line need fillings? Options from simple to involved
Not every notch needs a filling. These options are usually combined, starting at the top.
| Option | When it fits | What to expect |
|---|---|---|
| Brushing and toothpaste review | Every case | A soft brush, gentle technique and a low-abrasion fluoride toothpaste |
| Desensitising care | Sensitive but shallow notches | Desensitising toothpaste and in-clinic fluoride varnish or desensitiser; see sensitive teeth |
| Monitoring | Small notches without symptoms | Checked at regular visits with photos or scans |
| Bonded filling | Deep, sensitive, plaque-trapping or unsightly notches, or ones near the nerve | A tooth-coloured filling bonded into the notch, usually under local anaesthetic only if needed |
| Night guard | Grinding or clenching | A custom night guard to protect teeth and fillings from grinding forces |
| Treating acid causes | Signs of erosion | Diet changes, and a medical review if reflux is suspected |
| Gum treatment | Notches with significant gum recession | Gum assessment; a gum graft may be considered for some cases, and your dentist explains whether it suits you |
Fillings at the gum line can come loose more often than other fillings if grinding forces continue, which is one reason the causes are treated too.
What not every case needs
What gum line notches usually need, and what they usually do not
Most notches are a slow, manageable problem.
Usually enough
- A gentler brush and technique
- A lower-abrasion fluoride toothpaste
- Less frequent acid contact, and not brushing straight after acid
- A filling when the notch is deep, sensitive or hard to clean
Not usually needed
- Crowns or veneers just for gum line notches
- Filling every small notch the day it is noticed
- Whitening toothpaste, which can be more abrasive
- Root canal treatment, unless the nerve is involved

Patient questions
Frequently asked questions
What causes V-shaped notches in teeth at gum line?
Sharp V-shaped notches are usually linked to a combination of hard or scrubbing brushing and biting stress, sometimes called abfraction, where heavy biting or grinding flexes the neck of the tooth. Acid erosion often adds to the loss by softening the surface. A dentist looks at the shape, the teeth affected and your habits to judge which causes matter most for you.
Are gum line notches from brushing too hard or from grinding?
Often both. Brushing with hard bristles or a sawing action wears the neck of the tooth, especially where the gum has receded, and grinding may add stress at the same spot. Notches that are deeper on the side opposite your brushing hand point to brushing; wear facets on the biting edges point to grinding. Treating both is the surest way to slow further loss.
Do notches in teeth at gum line need fillings?
Not always. Small notches without symptoms can be monitored once the causes are addressed. A bonded tooth-coloured filling is usually recommended when a notch is deep, sensitive, trapping plaque, close to the nerve or bothering you cosmetically. The filling protects the exposed dentine but does not stop the causes, so brushing, acid and grinding still need attention.
Will gum line notches get worse if I leave them?
They can get slowly deeper while the causes continue, because lost tooth does not grow back. With a softer brush, gentler technique, less acid and protection from grinding, many stay stable for years. Photographs or scans at check-ups show whether a notch is changing and help decide when a filling becomes worthwhile.
Why do my gum line notches feel sensitive?
The notch exposes dentine, which contains tiny channels running towards the nerve. Cold, sweet food, air and brushing move the fluid in those channels and cause a short, sharp twinge. Desensitising toothpaste, fluoride varnish or a bonded filling over the notch usually reduce it. Pain that lingers or starts on its own should be checked, as it may mean something else.
Why do fillings in gum line notches sometimes fall out?
These fillings sit where the tooth flexes under biting forces and where the surface is partly root dentine, which is harder to bond to than enamel. Grinding and heavy biting can loosen them over time. Careful bonding, the right filling material and a night guard for grinders all help, and a lost filling can usually be replaced.
Can a gum graft cover notches at the gum line?
Sometimes, when a notch sits on root surface exposed by gum recession. A gum graft may be considered for some cases, occasionally together with a small filling, and your dentist explains whether it suits you and how it would be arranged. Many notches do not need gum surgery and are managed with brushing changes, desensitising care or a bonded filling.
