Her Gums Bleed Every Morning And Are Pulling Back. Here Is What I Told Her To Do At Home First.

A 63-year-old reader's dentist mentioned a gum graft. As a dermatologist I see a collagen problem, and a 12-minute daily routine that reaches it.

I read every letter that comes in. This week, more than half were about gums.

This week's letter

Dear Dr. Elena,

I'm 63. My dentist says my gums are receding and wants to talk about a graft. My teeth look longer every year, and my gums bleed every morning when I brush. I floss, I use the rinse he gave me, and it keeps getting worse.

Is there anything I can do at home first?

Reader, Ohio
Worried in OhioReader, age 63

Dear Worried,

First, keep that appointment. A graft is a real conversation to have with your dentist, and you should have it with all the facts.

But I can tell you what is happening in your mouth, and what you can start at home tonight, because I watched it happen to my mother and then I saw it start in my own mouth.

My mother brushed twice a day and still lost her teeth

My mother brushed twice a day her whole life. Her gums bled a little in the mornings, then looked puffy, then slowly pulled back until her teeth looked long. Her dentist said what yours is saying: keep it clean and we'll keep an eye on it.

She ended up in a full denture. Her teeth were never the problem. The tissue holding them gave way.

At 52 I saw my own gum line pulling back from one lower tooth, exactly the way hers did. That is when I stopped thinking like a daughter and started thinking like a dermatologist.

Your gums are made of collagen, and collagen slows down after 50

For 24 years I have worked with one tissue: collagen, the protein that keeps skin firm. Gums are made of the same thing. Collagen fibres anchor your gum tissue to the root of each tooth and keep it snug around the neck of the tooth.

After 50 the body makes less collagen every year. On your face that shows as thinner, looser skin. In your mouth it shows as gums that look thinner and redder, bleed when you brush and pull back from the teeth. That is why your teeth look longer every year.

Why brushing, flossing and rinses don't reach it

You are doing the right things. Keep doing them. But a toothbrush, floss and a rinse all work on the surface: they clear plaque and bacteria off the teeth and the gum line.

None of them reach the collagen layer underneath, which is where the firmness of your gums comes from. That is how someone can brush perfectly and still watch their gums recede.

What red and near-infrared light do

Cross-section of a tooth and gum: red light reaches the surface, near-infrared reaches the collagen layer
Red light, 630nm. Reaches the surface of the gum and calms red, puffy, irritated tissue.
Near-infrared, 850nm. Passes deeper, to the layer where the gum's collagen is made.

In dermatology we have used red and near-infrared light on aging skin for decades. Red light at 630nm calms inflamed, irritated tissue. Near-infrared at 850nm passes deeper and supports the cells that make collagen. It is gentle, warm at most, and nothing about it is sharp.

Nobody had put it where my mother needed it: at the gum line.

So I had a mouthpiece built

Dr. Elena Matthews holding the GumLight mouthpiece
The mouthpiece I use every evening. It sits along the whole gum line, top and bottom.

I worked with an engineer on a soft, clear mouthpiece lined with 32 LEDs, red and near-infrared, that covers the whole gum line. It is cordless and charges on a small round base. You bite down gently, press one button, and it runs a 12-minute cycle and switches itself off. I use mine in the evening while I read.

We called it GumLight. Within a few weeks my gums bled less when I brushed. By two months they looked pinker and felt firmer than they had in years.

What 30 volunteers noticed in 60 days

I did not want to rely on my own mouth, so I asked 30 volunteers aged 51 to 74, all with gums that bled or were pulling back, to use it at home every day for 60 days alongside their normal dental care.

Less bleeding when brushing by day 3083%
Said their gums looked pinker77%
Said their gums felt firmer by day 6087%
Kept using it after the 60 days90%

Home use, 12 minutes a day, alongside each volunteer's usual brushing, flossing and dental visits.

What I would do in your place

GumLight on its charging base on a kitchen table
Twelve minutes, once a day. It charges on its base between uses.
  1. Keep your dentist appointment and your cleanings. Ask about the graft, and ask for your gum measurements so you have a starting point.
  2. Keep brushing gently twice a day and keep flossing.
  3. Add 12 minutes of red and near-infrared light at the gum line every day, so the tissue underneath gets attention too.
  4. Look again in six weeks: bleeding, colour, how firm they feel. Write it down and show your dentist.

Start now, before anyone mentions dentures. Early is the best time to look after the gums you have.

Dear Dr. Elena, will it hurt? My teeth are sensitive and I flinch when the hygienist uses the cold air.

Reader, Arizona
Nervous in TucsonReader, age 58

Dear Nervous,

It won't. There is no heat you would call hot, no vibration, no needles, and the only thing touching your mouth is a soft, smooth mouthpiece. Light doesn't trigger cold sensitivity. Most of my volunteers forgot it was in after a few minutes and read or watched TV.

Dear Dr. Elena, I already wear a partial on the bottom. Is it too late for the rest of my gums?

Reader, Georgia
Hopeful in GeorgiaReader, age 70

Dear Hopeful,

No. The gums around your remaining teeth are still collagen, and they still deserve attention every day. Take the partial out, run the 12 minutes, put it back. Looking after the teeth you have is the whole point.

Dear Dr. Elena, my husband's gums bleed every time he flosses. He says that's normal at our age. Is he right?

Reader, Oregon
Concerned in OregonReader, age 66

Dear Concerned,

Common, yes. Normal, no. Healthy gums don't bleed when they are touched; bleeding means the tissue is inflamed. Have him mention it at his next cleaning and keep flossing. Then do what a lot of couples who write to me do: get one each and sit down together for the 12 minutes in the evening.

Dear Dr. Elena, how long before I notice anything?

Reader, Texas
Impatient in TexasReader, age 61

Dear Impatient,

Most of my volunteers said their gums bled less when brushing within the first two to three weeks. Colour and firmness take longer: give it six to eight weeks of daily use. It is a routine, like skincare. It works because you do it every day.

My answer to every letter this week comes back to the same thing: keep seeing your dentist, and start the 12 minutes at home now, while the sale is on.
