White spots may be a symptom of canker sores, oral thrush, oral lichen planus, leukoplakia and other infections.

White spots on the gums may indicate:

  • A canker sore - If it’s painful or has a white or yellow center.
  • Leukoplakia - If the white spots are thicker or more like painless white or gray patches it may be a sign and symptom of leukoplakia. Some leukoplakia can be a sign of increased risk of developing oral cancer.
  • Oral thrush – Caused by the overgrowth of candida albicans and may appear as thick patches that can be wiped off.
  • Oral lichen planus – An inflammatory condition that can create a lace-like network of white lines or patches in the mouth. It is not contagious.

Oral Hygiene Tips to Help Gum Health

Healthy gums are crucial to tooth and mouth health. In the event of gum disease (also known as gingivitis), the first line of defense is to see a dental professional. They can do a proper examination, determine the level of periodontal disease, and recommend treatments. But there are things you can do to help.

  • Oral-B iO electric toothbrushes help protect your teeth and gums. Studies show they can be more effective at improving gum health than manual toothbrushes. For those with advanced gum issues like periodontitis, an Oral-B iO toothbrush with brushing app has been shown to enhance disease management when used as part of a comprehensive care plan.
  • Crest Gum Detoxify Toothpaste is formulated with stannous fluoride. Use with an Oral-B iO toothbrush so the ingredients in the paste can reach along the gumline to help neutralize plaque bacteria for 24 hours (with twice-daily brushing), giving you healthier gums.
  • Brush heads like Oral-B iO Gentle Care brush heads feature up to 4,000 ultra-thin bristles for a gentle, effective clean. When paired with an Oral-B iO toothbrush, the brush head's micro-vibrations help loosen plaque. Additionally, the smart pressure sensor located in the iO handle helps protect you from brushing too hard.
  • Rinsing with a mouthwash like Crest Pro-Health Clinical is clinically proven to provide 24-hour protection against plaque and gingivitis with twice-daily use.
  • Glide Floss removes plaque between teeth and helps prevent gingivitis as part of a complete dental plan.
