When considering the factors that influence dental health, one crucial element often goes unnoticed: water quality. In Australia, where the water supply is generally well-regulated, we might take for granted the role that clean water plays in maintaining our oral health. However, the latest research underscores the importance of water quality and compels us to take a closer look at its impact on our teeth and gums.

Water is the most consumed liquid, pivotal for life and health, including that of our teeth. Fluoridation of public water has been hailed as one of the most significant health achievements of the 20th century. By adjusting fluoride to optimal levels, many communities have seen dramatic declines in tooth decay. The fluoride found in community water supplies strengthens tooth enamel, making it resistant to the acid attacks that cause tooth decay.

Beyond fluoridation, the mineral content of water – particularly calcium and phosphate – can influence dental health. These minerals can contribute to the remineralisation of tooth enamel, acting as a natural defence against cavities. Hard water, with higher levels of these minerals, can provide an extra layer of protection. Yet, it’s not just about the minerals added to water, but also about the impurities that must be removed. Contaminants such as lead, which can leach into water from old pipes, pose significant health risks, including to our oral health.

The pH level of water also holds significance for dental health. Acidic water can contribute to enamel erosion, while alkaline water may help neutralise the mouth’s acidity. Water’s pH can be affected by various factors, including industrial pollution and natural environmental variations. It’s a delicate balance that water treatment plants manage to ensure the water that reaches our homes is safe and beneficial for consumption and our teeth.

Another dimension of water quality is its role in oral hygiene. Clean water is essential for brushing and rinsing, playing a direct role in removing food particles and bacterial plaque. It’s an integral component of oral hygiene routines that safeguard dental health.

In our practice, we advise patients not only about their brushing and flossing habits but also about the importance of being aware of their water quality.

In conclusion, water quality is a silent ally in the fight against dental decay. It’s a testament to modern science’s ability to harness nature’s resources for the betterment of our health. As dental professionals, we celebrate the triumphs of water treatment and fluoridation, and we advocate for the continued vigilance and research that ensures the water we drink continues to contribute to our dental and overall health.
