If you've been told you have gum disease, you might be referred to a periodontist. But what exactly do they do? A periodontist is a dental specialist who focuses on the gums, bone, and other structures that support your teeth.

Here's what periodontists treat, how they differ from general dentists, and when you might need one.

01

What Periodontists Treat

Their specialty:
The supporting structures of teeth—gums, periodontal ligaments, and jawbone. "Perio" means around, and "odont" means tooth.

Conditions they treat:

  • Gingivitis (early gum disease)
  • Periodontitis (advanced gum disease)
  • Gum recession
  • Bone loss around teeth
  • Gum infections

Procedures they perform:
  • Scaling and root planing (deep cleaning)
  • Gum surgery (pocket reduction)
  • Gum grafts
  • Bone grafts
  • Dental implant placement
  • Crown lengthening
  • Treatment of gummy smile

02

Periodontist vs General Dentist

Education:
  • General dentist: 4 years dental school
  • Periodontist: 4 years dental school PLUS 3 years specialized training

What this means:
Periodontists complete additional training focused on gum disease, gum surgery, and dental implants.

What they see:
Periodontists focus on moderate to severe gum disease cases that need more intensive treatment than regular cleanings provide.

Equipment and expertise:

  • Specialized surgical instruments
  • Training in grafting techniques
  • Expertise in implant placement
  • Advanced treatment of gum disease

03

When You Need a Periodontist

Your dentist may refer you for:

Gum disease treatment:

  • Moderate to severe periodontitis
  • Gum disease not responding to regular treatment
  • Deep pockets around teeth (4mm+)
  • Bone loss visible on X-rays

Surgical needs:
  • Gum grafting for recession
  • Pocket reduction surgery
  • Bone regeneration
  • Crown lengthening before dental work

Implant placement:
  • Many periodontists place implants
  • Complex implant cases
  • Cases needing bone grafting

When general dentist is fine:
  • Mild gingivitis
  • Routine cleanings
  • Early gum disease responding to treatment

04

What to Expect at a Periodontist

First visit:
  • Comprehensive periodontal exam
  • Measuring pocket depths
  • Assessing bone levels on X-rays
  • Discussing diagnosis and options
  • Treatment planning

Common treatments:
  • Scaling and root planing: Deep cleaning below the gumline
  • Pocket reduction surgery: Reducing deep pockets
  • Gum grafting: Covering exposed roots
  • Bone grafting: Rebuilding lost bone

After treatment:
  • Maintenance cleanings (usually every 3-4 months)
  • Ongoing monitoring
  • May return to general dentist for routine care

05

Signs You Might Need a Periodontist

Warning signs of gum disease:
  • Bleeding gums when brushing or flossing
  • Red, swollen, or tender gums
  • Gums pulling away from teeth
  • Loose or shifting teeth
  • Persistent bad breath
  • Pus between gums and teeth
  • Changes in bite

Risk factors:
  • Smoking
  • Diabetes
  • Family history of gum disease
  • Poor oral hygiene
  • Certain medications

Why treatment matters:
Untreated gum disease leads to bone loss and tooth loss. It's also linked to heart disease, diabetes complications, and other systemic health issues.
Summary — Key takeaways

Key Takeaways

A periodontist is a gum disease specialist who treats conditions affecting the supporting structures of teeth. They handle cases beyond what regular dental cleanings can address and perform surgeries to restore gum and bone health.

If your dentist recommends seeing a periodontist, it's because your gums need specialized care. Early treatment is key—gum disease is much easier to manage before significant bone loss occurs.
