Seeing pink in the sink when you brush is common, but it isn’t normal. Healthy gums don’t usually bleed with gentle brushing or flossing. Bleeding is often the first sign that your gums are inflamed.
Common causes
- Gingivitis: inflammation caused by plaque along the gumline. This is the most common cause.
- Brushing too hard or using a hard-bristled brush
- Starting a new flossing routine
- Hormonal changes, especially during pregnancy
- Some medications, such as blood thinners
- Less commonly, medical conditions such as diabetes, vitamin deficiencies or blood disorders
Gingivitis and gum disease
Plaque that isn’t removed releases toxins that irritate the gums, making them red, swollen and prone to bleeding. At this stage, gingivitis is reversible with good cleaning. If it is left untreated, it can progress to periodontitis. This deeper infection damages the bone that holds teeth in place, and can lead to loose teeth and tooth loss.
What you can do at home
- Brush twice daily with a soft brush, paying attention to the gumline.
- Clean between your teeth every day.
- Don’t stop brushing an area because it bleeds; gentle cleaning helps it heal.
- Stop smoking, which hides bleeding and worsens gum disease.
When to see a dentist
Book a check-up if bleeding lasts longer than two weeks, or if you notice swelling, bad breath, receding gums or loose teeth. A professional clean removes hardened tartar, which brushing can’t. Your dentist can also check whether the gum disease has gone deeper.
