Gums that bleed when you brush are the single most common problem we see mid-treatment, and the instinct almost everyone has is exactly wrong.
The instinct is to brush that area less because it hurts and bleeds. The bleeding is caused by not cleaning it enough. Brushing less makes it worse — which makes it bleed more, which makes you brush even less.
What is actually happening
Brackets create sheltered spots that a toothbrush skips over unless you aim at them deliberately. Plaque settles along the gumline, the gum reacts by becoming inflamed, and inflamed gum tissue bleeds when touched.
That’s gingivitis. It’s common, it’s reversible, and with consistent cleaning it usually settles within one to two weeks.
Sometimes gums also become puffy and grow slightly over the brackets. That’s an overgrowth response to the same irritation, and it recedes once the area is clean — though it can take longer than the bleeding does.
What to do
Brush the gumline, not just the teeth. Angle the brush at 45 degrees toward where the tooth meets the gum, and use small circles. Above and below every bracket, deliberately. Two minutes, after every meal.
Floss daily, properly. This is the step people skip, and it’s the one that fixes it. Use a floss threader or orthodontic floss to get behind the wire, and go beneath the gumline on each side of every tooth. Our brushing and flossing page walks through the technique.
Rinse with warm salt water. One teaspoon in eight ounces of warm water, twice a day. It calms inflamed tissue while the cleaning does the real work.
Expect it to bleed for a few days. This is the part worth bracing for. Cleaning an inflamed gum makes it bleed at first. Keep going gently and it stops — usually within a week or two. Bleeding that continues past two weeks of genuinely good cleaning is a different conversation.
Ask us about a water flosser if threading floss is defeating you. It isn’t a replacement, but for some people it’s the difference between doing it and not.
When to call us
- Bleeding still there after two weeks of consistent cleaning
- Gum that is painful and swollen around one specific tooth, rather than generally puffy — that can indicate something other than gingivitis
- Any swelling in the face, or a bad taste that won’t clear
- Gum growing far enough over a bracket to bury it
Call (212) 966-9628. Our emergency care page covers the other mid-treatment problems.
Why it matters beyond comfort
Inflamed gums slow treatment down. Teeth move through healthy bone predictably; inflamed tissue is less cooperative. And badly inflamed gums can leave permanent marks on the teeth once braces come off — which is a poor trade for two weeks of better brushing.
Keep your six-monthly cleanings with your dentist too. They matter more during treatment, not less.
Worried about how your gums look? Bring it up at your next visit, or call us. We’d far rather look at it early.
