Most dental problems are preventable, and the prevention is unglamorous. Three habits do the overwhelming majority of the work, and none of them require willpower so much as knowing why they matter.
Dental problems can be a real pain, both literally and figuratively. By following these three simple tips, however, you can help to avoid many common dental problems. First, make sure to brush your teeth twice a day with a fluoride toothpaste. Second, floss at least once a day. And finally, see your dentist near you in London for a check-up at least once a year.
1. Brush your teeth twice a day and floss regularly.
Your dentist wants you to brush your teeth twice a day and floss regularly. Flossing helps remove plaque and bacteria from in between your teeth and along your gum line. Plaque can cause tooth decay and gum disease.
2. See your dentist for checkups and cleanings twice a year.
Dentists recommend that you see them for checkups and cleanings twice a year. This helps them to catch any problems early on and to keep your teeth healthy.
3. Avoid sugary snacks and drinks.
One way to avoid sugary snacks and drinks is to make sure that you always have healthy snacks and drinks available. This means keeping fruits and vegetables handy, as well as water and unsweetened tea or coffee. If you do find yourself reaching for a sugary snack, try to make it a smaller portion and save the rest for later.
Three Habits That Prevent Most Dental Problems
These are the changes with the strongest evidence behind them, consistent with Canadian Dental Association guidance.

1. Brush twice with fluoride — and do not rinse
Two minutes, soft bristles angled into the gumline, small circles rather than scrubbing. Then spit and do not rinse. Rinsing washes away the concentrated fluoride you just applied, and stopping it measurably reduces decay. This single change is the cheapest way of avoiding dental problems available to anyone.
2. Clean between the teeth every night
A toothbrush reaches roughly three of five tooth surfaces. The remaining two are where most decay between teeth and most gum inflammation begin. Floss works; interdental brushes usually work better where the gaps allow, and people use them more consistently. The best tool is whichever one you will genuinely use.
3. Reduce how often you eat sugar, not just how much
Each exposure drops the pH in your mouth for a period afterwards, and it is the number of those acid attacks that drives decay. Six small snacks do more damage than one dessert. Sipping a sweetened coffee across a whole morning is one of the most common causes of dental problems seen in practice.

Warning Signs Worth Acting On Early
Pain is a late signal. These appear much earlier.
Bleeding when you brush
Healthy gums do not bleed. This is the earliest reversible stage of gum disease and the easiest point to intervene.
Sensitivity to cold that lingers
Brief sensitivity is common; pain that continues for a minute after the cold is removed suggests the nerve is involved and needs assessment.
A rough edge, or food catching in a new place
Often the first sign of a fractured filling or decay between teeth. Both are simple to fix early and expensive to fix late.
Morning jaw ache or worn edges
Suggests nocturnal grinding, which cracks fillings and wears enamel. A night guard prevents dental problems that would otherwise need crowns.
When to seek help urgently
Spreading facial swelling, difficulty swallowing or breathing, or fever with swelling means hospital rather than a dental chair; overnight, Health811 advises free of charge. Otherwise, risk-based check-ups catch nearly everything above while it is still cheap. Fees reference the Ontario Dental Association guide under Royal College of Dental Surgeons of Ontario standards. See our hygiene page, emergency page, or book an appointment.

Prevention works best when the whole household is on the same schedule. Our guide to a family dentist in London explains what care each age group needs and how often to attend.
Prevention is cheaper than repair, which is why routine teeth cleaning matters more than most people expect, and why dental fillings are best done early. More at Hyland Dental Centre.
