How to prevent gum disease

Gum disease is one of the most common reasons adults lose teeth, yet it is often painless in its early stages. The good news: it is largely preventable, and treatable when caught early.

Published October 2026

What gum disease is

Bacteria in plaque, the sticky film that builds up on teeth every day, irritate the gums. If plaque isn’t removed, it hardens into tartar that brushing can’t remove. The earliest stage, gingivitis, causes red, puffy gums that may bleed when you brush or floss. At this point the damage is reversible.

Without treatment, gingivitis can progress to periodontitis. The gums pull away from the teeth, forming pockets where bacteria collect, and the bone and ligaments that hold teeth in place begin to break down.

Signs to watch for

  • Gums that bleed when you brush or floss
  • Red, swollen or tender gums
  • Bad breath that doesn’t go away
  • Gums that are receding, making teeth look longer
  • Increased sensitivity
  • Teeth that feel loose or a bite that feels different

Who is at higher risk

Anyone can develop gum disease, but the risk is higher for people who smoke or use tobacco, have diabetes, have a family history of gum disease, or are going through hormonal changes such as pregnancy. Some medications that cause dry mouth can also raise the risk.

Everyday prevention

  • Brush twice a day for two minutes, angling the bristles toward the gum line
  • Floss or use interdental brushes daily to clean where your toothbrush can’t reach
  • Don’t smoke, or get help to quit
  • Eat a balanced diet and limit sugary snacks
  • Keep your cleanings: professional cleanings remove the tartar that home care can’t

If you already have symptoms

Don’t wait for it to hurt. Depending on the stage, treatment can include periodontal cleanings, scaling and root planing to clean below the gum line, laser therapy and antibiotics. The earlier we start, the simpler the treatment, so give us a call if your gums have been bleeding.
