Why Do Gums Bleed? When Should You See a Dentist?

Gums bleeding while brushing or flossing is a common problem. However, being common does not make it normal. Bleeding gums are often the first sign of inflammation starting in the gum tissue.

Common Causes of Bleeding Gums

Bacterial Plaque and Tartar

When bacterial plaque that builds up on the tooth surface is not removed, it leads to gum inflammation (gingivitis). Over time, plaque hardens into tartar, which cannot be removed by brushing at home.

Incorrect Brushing Technique

Using a hard-bristled toothbrush or pressing too hard while brushing can irritate the gums.

Hormonal Changes

Hormonal changes during periods such as pregnancy and puberty can make the gums more sensitive.

Systemic Conditions and Medications

Diabetes, certain blood disorders and blood-thinning medications can contribute to bleeding gums. That is why it is important to share your medical history with your dentist.

Symptoms That May Accompany It

• Red, swollen or tender gums
• Bad breath
• Receding gums
• Tooth sensitivity or loose teeth

When Should You See a Dentist?

An examination is recommended if your gums bleed for more than a few days, bleed on their own, or if the bleeding comes with swelling, pain or loose teeth. With a professional cleaning and proper oral care in the early stages, gum inflammation can usually be brought under control. In more advanced cases, periodontal treatment may be needed.

What Can You Do at Home?

• Brush gently twice a day with a soft-bristled toothbrush
• Clean between your teeth once a day with dental floss or an interdental brush
• Do not stop flossing because of the bleeding; regular use helps reduce inflammation
• Consider quitting smoking
• Keep up with dental checkups every 6 months
