Why do my gums swell after brushing
Gums that swell after brushing may be inflamed, irritated by technique, or affected by plaque, tartar, infection, or another condition.
The short answer
Gums that swell after brushing may be inflamed, irritated by technique, or affected by plaque, tartar, infection, or another condition. Bleeding or swelling that keeps returning is not explained by brushing alone and needs an oral examination.
How can plaque and tartar cause gum swelling?
Plaque bacteria can inflame the gingiva at the gum margin, while hard tartar cannot be removed with a toothbrush. A hard-bristled brush, excessive pressure, a new brushing routine, mouth breathing, or a local injury can also irritate gum tissue.
How can you brush gently when your gums are swollen?
Use a soft-bristled brush with gentle circular strokes at the gumline and clean between the teeth daily. Do not stop cleaning the area, but arrange professional removal of tartar if deposits remain.
When should recurring swelling after brushing be examined?
Book a dental examination when swelling persists, bleeds often, causes bad breath, or affects one specific area. Seek urgent care for facial swelling, fever, severe pain, pus, or difficulty swallowing.
What condition could be causing swelling after brushing?
Ask whether the swelling is gingivitis, periodontitis, trauma, an abscess, or a reaction to a product. Ask whether you need scaling, a change in brushing technique, treatment of a decayed tooth, or evaluation of a medication or medical condition.
Frequently asked questions
Should I keep brushing swollen gums?
Yes, clean gently with a soft brush while arranging an examination if the problem continues.
Can tartar make gums swell?
Yes. Tartar provides a rough surface that can retain plaque and usually needs professional removal.
