It Starts With a Smile.

Smoking and its effects on oral health...

A major problem of smoking is that it tends to disguise the damage taking place to teeth and gums... 

Usually infected gums are red, puffy and bleed easily when they are brushed. Smokers' gums are not like this - they are pale and thin and do not bleed readily.

The nicotine in tobacco smoke is called a vaso-constrictor - it acts on blood vessels to contract them, reducing the blood flow to the gum and bone. The decreased blood supply does two things; it masks the signs of disease and also undermines the body's ability to combat any infection.

In addition, chemicals in the smoke combined with plaque bacteria create a dangerous combination. X-rays taken of the teeth of even young smokers usually show that bone support has begun shrinking away from the tooth roots. Most of the deterioration is deep and out of sight and there are only a few early warning signs.  At Drummoyne Dental Practice we have digital radiography available.

Nicotine also has a profound effect on the saliva, promoting the formation of the thicker ‘mucous’ form of saliva at the expense of the thinner watery ‘serous’ saliva which is instrumental in counteracting the effects of acid attack after eating. This effect of nicotine explains why some heavy smokers get decay even if they are brushing well.  There are some handy hints which our dentists can give in regard to increasing saliva flow and counteracting the effects of dry mouth.

Smokers are six times more likely to have serious gum (periodontal) disease that can involve not just the pink gum but also the supporting bone and the membrane that holds the teeth in place. In advanced gum disease, teeth can become loose and eventually need to be extracted.  Our dentists will usually only consider extraction of teeth as a last resort.  At Drummoyne Dental Practice we believe in conservation of natural tooth structure whenever possible.

It is important to understand is that smoking can hide the signs of gum disease for years and the condition can be very advanced before a smoker notices any damage. Slight infections around the edges of the gums are common and easily treated, but smoking allows the condition to progress more deeply and seriously.

Flossing and careful brushing tends to slow down the deterioration, but smokers often have reduced sensation in their mouths and it is difficult to detect and remove all the plaque at the gum margins.  

Besides the damage to teeth and gums that smoking can cause, it still remains the single biggest risk factor in contracting oral cancer. You can read about this in the Oral Cancer Screening section of this website where you’ll find detailed information on its causes, symptoms and early detection.
