Tartar Under the Gums: Signs & Risks

Tartar under the gums is harder to see and more dangerous than surface buildup. While visible tartar affects appearance, subgingival tartar threatens gum health and bone support.

Because it forms below the gumline, many people do not realize it is there.

By the time symptoms appear, inflammation may already be progressing.

Understanding hidden tartar helps you act early and prevent long-term damage.

What Is Subgingival Tartar?

Subgingival tartar is hardened plaque that forms below the gumline.

It develops when plaque is not fully removed near the gum margin. Over time, saliva minerals combine with bacteria and harden the deposit.

Unlike surface tartar, it:

• cannot be seen easily

• cannot be brushed away

• often feels smooth to the tongue

• may not cause pain at first

This makes early detection difficult without professional examination.

How Tartar Below the Gumline Forms

Plaque collects along the gum edge daily.

If not disrupted within 24–72 hours, minerals in saliva begin hardening it.

When plaque accumulates slightly below the gumline, the same mineralization process occurs.

However, once tartar forms under the gums:

• bacteria become trapped

• toxins irritate tissue

• inflammation deepens

• gum pockets expand

This cycle can continue silently.

Early Signs of Tartar Under Gums

Because it is hidden, symptoms are often indirect.

Watch for:

• bleeding when brushing

• swollen or puffy gums

• persistent bad breath

• mild tenderness

• gum recession

These signs suggest irritation beneath the surface.

Even if teeth look clean, hidden tartar may be present.

Why Subgingival Tartar Is More Dangerous

Tartar below the gumline affects supporting structures.

It can:

• weaken gum attachment

• damage connective tissue

• contribute to bone loss

• deepen periodontal pockets

• increase tooth mobility

The bacteria trapped beneath hardened deposits produce toxins continuously.

These toxins trigger the body’s inflammatory response.

Over time, chronic inflammation damages surrounding structures.

The Link Between Subgingival Tartar and Gum Disease

Subgingival tartar is strongly associated with periodontitis.

When tartar builds below the gumline:

1. Gum tissue becomes inflamed.

2. Pockets form between tooth and gum.

3. Bacteria multiply inside pockets.

4. Bone support begins to decline.

Because this process may not cause severe pain early, it often progresses unnoticed.

Routine dental visits are critical for detection.

Can You Feel Tartar Below the Gumline?

Sometimes you may notice:

• roughness near the gum edge

• slight pressure sensation

• localized swelling

• bleeding in specific areas

However, deep deposits cannot be felt directly.

Only periodontal probing and scaling reveal their extent.

That’s why professional assessment matters.

How Dentists Remove Hidden Tartar

Subgingival tartar requires specialized removal techniques.

Dentists or hygienists use:

• ultrasonic scalers

• manual curettes

• root planing techniques

Ultrasonic vibration loosens hardened deposits.

Manual instruments refine cleaning beneath the gumline.

In deeper cases, root planing smooths the tooth surface to discourage future buildup.

This process restores a healthier environment for gum healing.

What Happens If It Is Not Treated?

Untreated tartar under the gums can lead to:

• chronic bleeding

• gum recession

• bone deterioration

• tooth shifting

• eventual tooth loss

The progression is often gradual.

Because pain is minimal early on, many people delay treatment.

Unfortunately, advanced periodontal damage is harder to reverse.

Prevention is simpler than repair.

How to Reduce Risk of Subgingival Tartar

While professional removal is essential, daily habits reduce recurrence.

1. Focus on the Gumline

Angle your toothbrush 45 degrees toward the gum margin.

2. Floss Consistently

Floss removes plaque before it slips under the gum edge.

3. Use Antibacterial Support

Reducing bacterial load lowers mineralization risk.

4. Schedule Cleanings Every 6 Months

Some individuals benefit from more frequent visits.

5. Address Dry Mouth

Low saliva flow increases plaque buildup speed.

Consistency prevents hidden accumulation.

Who Is at Higher Risk?

Certain individuals develop subgingival tartar more easily:

• smokers

• people with diabetes

• individuals with crowded teeth

• those with poor flossing habits

• people with existing gum inflammation

If you fall into these groups, proactive care becomes even more important.

Key Takeaway

Tartar under the gums is not just cosmetic. It affects the structures that hold your teeth in place.

Because it is hidden, it often progresses without obvious warning.

Regular professional cleanings combined with consistent daily plaque disruption are the best defense.

Healthy gums protect long-term tooth stability.

FAQ – Tartar Under the Gums
