What actually keeps teeth: a dentist's short list

5 min readDr Nils Bergqvist, Dentistry

Brushing technique matters less than timing, and flossing matters less than most people have been told. What matters is boring.

Almost all adult tooth loss comes from two processes: decay and gum disease. Both are largely preventable, and both are driven less by how hard you brush than by how often sugar is in your mouth and whether plaque is removed daily.

Frequency of sugar, not quantity

A whole chocolate bar eaten at once does less damage than the same bar eaten in six pieces across a day. Each exposure drops the pH and the recovery takes time, so six exposures means six acid attacks.

The single most effective change most patients can make is not eating less sugar but eating it less often.

Do not rinse after brushing

Rinsing washes away the fluoride that is the entire point of the toothpaste. Spit, and leave it. This one costs nothing and a surprising number of people have never been told it.

Interdental cleaning, using whatever you will actually use

Brushes that fit the gaps generally clear more plaque than floss, and either beats the option you abandon after a week. Consistency dominates technique here.

Bleeding gums are not normal

Gums that bleed when brushed are inflamed. At the earliest stage this is fully reversible with better daily cleaning. Left alone it becomes bone loss, and bone does not come back.

Grinding is worth mentioning

Worn edges, morning jaw ache and unexplained cracks usually mean grinding, often stress-related and often nocturnal. A guard is inexpensive next to rebuilding a worn dentition.
