Fluoridation is another controversy. The first criticism of adding fluoride to the water supply, which has been occurring through the Western world over the last 50 years, is that it is impossible to accurately determine dosage as people consume varying amounts of water. The obvious adverse effect of fluoride is irregular, mottled enamel, however there are also reports of hip fracture, cancer, joint and ligament calcification. Again studies and clinical observation vary as to the degree of this problem.

The positive effect of fluoridation is the reduction of tooth decay. In cities which have fluoridation, the reduction of tooth decay is certainly impressive. However research continues to challenge this connection and shows that non-fluoridated areas have shown similar reduction in rates of decay. This may be from the daily topical application of fluoride during brushing, which is thought to have a greater preventive effect against decay than the ingestion of fluoride in the water.

I have a higher than average number of homoeopathically orientated patients and many of these seek out fluoride free toothpastes. This group even with a mild intake of sugar have a higher than average incidence of tooth decay. My advice to patients is to reduce/eliminate the frequency of sugar intake. This will prevent tooth decay completely. Then there is no need for fluoride in toothpaste or water. If they cannot/will not control their diet, then they should use a fluoride toothpaste topically being careful not to swallow it. This will avoid the ingestion of fluoride and reduce tooth decay by up to 50%. Patients are advised to avoid the ingestion of fluoride in water by using an appropriate water filter.

My own feeling is that the fluoride issue is typical of the way western medicine approaches a problem. Rather than dealing with the cause, in this case very obviously being diet (high frequency of sugar intake), it looks for an additive to mask the problem. Not only will excellent dietary practices reduce our rate of decay and periodontal disease but will also have profound effects on our general health. This is the most basic premise of holistic dental practice philosophy.
