Dental IndiaWhen the snoring has to stop.....
Dentists may have the answer to the nightmare of noisy sleepers, says Christine Doyle HELP is at hand for those who snore with the force of a revving motorcycle - and for their distracted bedfellows and flatmates who try to blot out the din with earplugs Dentists are being trained to fit mouth guards, which are said to eliminate or significantly reduce the explosive noises in up to 80 per cent of snorers. Recently, the British Dental Association held its first anti-snoring workshop to teach dentists more about the causes and treatment of snoring and how to select the right guard for each patient. Dr Jacinta Yeo, the London dentist who ran the workshop, says: "For several years, a few dentists have been trying out the mouth guards with their patients, but most dentists do not know how to fit them or get the best out of the laboratory technicians who custom-make the devices. "We felt it was time to make a simple solution to snoring more widely known. Mouth guards are comfortable to wear and can help many heavy snorers. They are very popular in America." Karen Roth, 28, a dental nurse, heard about the mouth guard two years ago. "I thought I might as well try it, and have worn one called Silensor every night since. It has certainly done the trick. I am not a thunderous snorer - I don't think I could be, as I am quite tiny - but my boyfriend used to make pointed remarks in the morning and he worried about not getting a good night's sleep. "I don't know why I snore, but it runs in my family. My mother and grandmother are both lifelong snorers." Snoring is caused by air travelling rapidly through an obstructed airway, setting up vibrations in the soft palate, tonsils and uvula - the dangly bit at the back of the throat. The mouth guard, which Roth puts into her mouth before falling asleep, is designed to pull and hold the lower jaw forward. This creates space in the throat and prevents the back of the tongue and soft throat tissue collapsing and blocking the airway. At between £500 and £800, the anti-snoring guards are no giveaway, but their introduction could transform lives, says Dr Yeo. Around 30 per cent of women and 40 per cent of men snore. One professional woman, whose high-decibel roars were beginning to threaten her marriage, realised just how loud they were only when she heard fellow delegates at an overnight work conference complain they had been kept awake all night by snoring. She was mortified. John Bennett, 36, a senior marketing director, says he was once woken by a stewardess on a night flight because he was keeping everyone else awake. The woman with whom he lives has found it difficult to be tolerant. "John sent off for every gadget you can think of," says Angela Harvey. "He's tried nose-clips and pillows and I even sewed a tennis ball into his pyjamas to stop him rolling on to his back. Ear plugs did not blot out the noise and often I felt forced to sleep downstairs." After being fitted with a mouth guard called the Thornton Adjustible Positioner, or Tap, Bennett was astonished by the difference. "From the first night, I no longer felt sleepy during the day." The change was so instant, says Harvey, and the silence so eerie, that she used to check that he was still breathing. Bennett also has sleep apnoea, a condition in which the airway is so obstructed that the sufferer intermittently stops breathing. This can happen regularly during the night for around 10 seconds at a time and, in very severe cases, last up to 40 seconds, many times an hour. Sufferers jerk awake with unnerving grunts and gasps when oxygen in the brain dips to a low level. Frank Govan, chairman of the British Sleep Apnoea Trust and a sufferer himself, says the condition affects about four in every 1,000 people and can be life-threatening. In extreme cases, the dips in oxygen lead to irregular heart beat, high blood pressure and as much as 20 times the average risk of a heart attack. The BDA points out that most people with sleep apnoea snore, but not all snorers have sleep apnoea. "It is important for dentists to make the distinction and to work in conjuction with a sleep clinic where specialists can identify the anatomical cause and degree of blockage." People with severe sleep apnoea sometimes wear a mask which pushes oxygen into the lungs under slightly raised pressure. This works, but there are people who find the masks cumbersome and claustrophobic and who are converting to mouth guards. A study being carried out at the Churchill Hospital, Oxford, suggests the mouth guard will be helpful for heavy snorers and people with light to moderate apnoea, but less so for those with severe sleep apnoea. Mouth guards have three basic designs. One lifts the soft palate up, but some people find this makes them gag. Another holds the tongue forward, which is useful if you have no natural teeth. Most common are those, like the Silensor, that pull the lower jaw forward, and these have a high success rate. Maria Sergides, a dentist in Carshalton Beeches, says her patients get used to these quickly. She began to recommend them after trying one out on her father. "He kept us all awake, but now the household is peaceful." Roth says: "Your mouth feels a little strange, a bit stretched for a minute or so in the morning, but this soon wears off." They are definitely not romantic: "It's best not to make a big deal out of it. Not everyone likes wearing one, but I think they work well." Some snorers may also be able to help themselves by trying to cut out some pre-disposing factors - being overweight, eating large meals late at night, drinking too much beer and using sleeping pills. But for some people, none of these are influences. "Look at me," Roth says. "Who would expect a size eight to snore?"
