Why Less Is More for Your Teeth

Myth of the Week

Many patients believe that brushing harder means cleaner teeth. In reality, aggressive brushing does more harm than good. It wears down your enamel over time and causes your gums to recede, exposing the sensitive root surface underneath. The bristles do not need force to remove plaque; gentle, circular motions with a soft-bristled brush are far more effective. Think of it like washing a fine fabric: you would not scrub it with steel wool. Your enamel is the hardest substance in your body, but it is also irreplaceable once lost.

Quick Tip

After eating something acidic, like citrus fruits, tomato sauce, or fizzy drinks, wait at least 30 minutes before brushing. Acid temporarily softens your enamel, and brushing right away can wear it down. Instead, rinse your mouth with plain water immediately after eating. This neutralises the acid and helps your saliva do its job of remineralising and repairing the enamel surface naturally.

Under the Lens: Hydroxyapatite Toothpaste

Hydroxyapatite is a mineral that makes up 97% of your tooth enamel. Toothpastes containing nano-hydroxyapatite have gained attention as a fluoride alternative, particularly in Japan where they have been used for decades. Research suggests they can help remineralise early enamel lesions and reduce sensitivity by filling microscopic gaps in the tooth surface. They are generally well-tolerated and free of the taste issues some patients report with fluoride. However, the evidence base is still smaller than fluoride's, and they work best as part of a comprehensive oral hygiene routine rather than a standalone solution.

Did You Know?

Your teeth are alive. Beneath the hard enamel exterior, each tooth contains a network of living tissue called the pulp, complete with blood vessels and nerves. This is why a tooth can feel temperature, sense pressure, and even heal itself from minor damage through a process called tertiary dentin formation. Preserving this living core is the central goal of conservative dentistry.
