CHECK-UP:Aphthous ulcers can cause severe discomfort in the mouth and to the tongue, writes Marion Kerr
LATELY I'VE been getting small blisters on the edge of my tongue, and sometimes on my gums. It seems like too trivial a problem to go to my GP about, but they are really driving me mad. Any idea what these might be?
If they are small yellow or grey blisters, surrounded by a bright red halo, then they are most probably aphthous ulcers. A common complaint, it is estimated that about one in 10 people suffer with them.
Although what actually causes them is not clear, certain factors do seem to trigger them.
These include emotional or physical stress, injury from rough dental work and irritation from certain food.
They can also be caused by a sensitivity to chemicals in toothpastes and mouthwashes, while some female sufferers notice that they occur at specific times in their menstrual cycle, implying that they may have a hormonal cause.
Many sufferers experience a burning or tingling sensation in the gums for several hours prior to the ulcers appearing. For the first two or three days, eating or talking can result in great discomfort. Aphthous ulcers are very troublesome and may take up to 14 days to heal.
I've only been getting them since I gave up smoking. Is this just coincidental?
Research has shown that smokers have a lower incidence of aphthous ulcers, but don't use that as an excuse to start smoking again. You should avoid spicy or acidy food, citric fruits and salty nuts. When you have the blisters drink plenty of fluids, sipping through a straw to prevent discomfort. And in case the problem is caused by dental work, a visit to your dentist would be advisable.
In the meantime, what can I do to treat them?
Over-the-counter painkillers can help control the pain of aphthous ulcers, while applying a special anaesthetic gel applied to the ulcers and surrounding gums will help ease the burning and discomfort.
Try applying it before meals as it will minimise the pain associated with eating. A mild solution of salt and warm water used as a mouthwash will also promote healing. If the ulcers continue to bother you, then a visit to your GP would be advisable.
