Her Gums Bled Every Time She Brushed, So She Stopped Brushing

Quick answer: Bleeding gums in pregnancy are extremely common and are driven by hormonal changes amplifying the response to plaque. The instinct to brush less makes it considerably worse. Cleaning is safe at any stage of pregnancy and is the treatment.

The call

Twenty-six weeks, second baby, and a mouth that had become genuinely distressing. Miriam, 31, from RBS Gimmel, described gums that bled at the lightest touch, swollen enough that they had changed the shape of her smile, and a taste of blood most mornings.

She had reduced brushing to once a day, quickly, avoiding the worst areas. It had seemed the obvious response.

She also asked, before anything else, whether a cleaning was safe while pregnant. It is, and the fact that this question stops people from getting treated is the reason it is worth answering loudly.

What we found

Generalised marked gingivitis. The gum margins were red, glossy and swollen, with the papillae between the front teeth enlarged into rounded, bulbous shapes. Bleeding on probing at nearly every site. Heavy plaque and calculus, particularly behind the lower front teeth and around the upper molars — precisely the areas she had been avoiding.

Critically: pocket depths of 3 to 4mm, and no bone loss on the x-rays we had from before the pregnancy. This was gingivitis, which is reversible, rather than periodontitis, which is not. That distinction is the whole prognosis.

Why pregnancy does this. Raised progesterone and oestrogen increase the permeability of gum capillaries and alter the local immune response, so the tissue reacts far more vigorously to the same amount of plaque. The bacterial population shifts too. The result is that a level of plaque that would cause mild inflammation in a non-pregnant person causes dramatic inflammation now.

It typically starts around the second month, peaks around the eighth, and settles within a few months of delivery. Something in the region of half of pregnancies involve some degree of it.

Why brushing less is the wrong instinct. The bleeding comes from inflammation, and the inflammation is driven by plaque. Less brushing means more plaque means more inflammation means more bleeding. The cycle is self-reinforcing and she was three months into it.

There is also a wider reason not to leave it. Severe untreated gum inflammation in pregnancy has been associated in a number of studies with adverse outcomes including preterm birth. The evidence on whether treating it changes those outcomes is genuinely mixed, and it would be overstating things to promise otherwise — but nobody argues for leaving it untreated.

What we did

Two hygienist appointments, two weeks apart, positioned on her left side with the chair only partly reclined, kept to forty minutes, in the morning. Full removal of plaque and calculus above and below the gum margin. Local anaesthetic was available and she did not need it.

Technique, which was most of the value: a soft brush, twice daily, with the explicit instruction to brush through the bleeding for the first fortnight. Interdental brushes for the spaces. An expectation set clearly — it will bleed more before it bleeds less, and that is the tissue healing, not being damaged.

A third visit at eight weeks to check.

The outcome

Bleeding had reduced substantially by the second visit and was minimal by the third. The swelling of the papillae resolved over about six weeks.

She was reviewed three months after the birth, by which time the hormonal driver had gone and her gums were normal. No bone was lost, because it was caught while it was still gingivitis.

What to do if this happens to you

1. Keep brushing, especially where it bleeds. This is the single most important thing.
2. Expect it to bleed more for a fortnight, then settle.
3. Book a hygienist appointment. Cleaning is safe in pregnancy at any stage.
4. Say how many weeks you are so the appointment can be positioned and timed properly.
5. Use interdental brushes, not just a toothbrush.
6. Have a review a few months after the birth to confirm everything has settled.
