Prevention of Cavities
Reduce their risk of cavities
How We Help Prevent Cavities
Decay is caused by acid-producing bacteria that thrive on sugar and starch. Over time, this acid dissolves tooth enamel, creating cavities. With the right combination of professional care and home habits, most cavities are entirely preventable.
Professional Cleans
Regular scale and polish removes hardened plaque that brushing can't reach, the primary source of cavity-causing bacteria.
Fluoride Treatments
Professional fluoride strengthens enamel and can even reverse early-stage decay before a cavity forms.
Fissure Sealants
A thin protective coating applied to the chewing surfaces of back teeth, particularly effective for children and teenagers.
Dietary Counselling
We identify patterns in your diet that increase decay risk and give you practical, achievable guidance.
Decay Risk Assessment
Some patients are genetically or medically predisposed to higher decay rates. We assess and tailor your prevention plan.
Regular Check-Ups
Catching early-stage decay on X-ray means treatment is simpler, cheaper and less invasive than waiting.
Daily Habits That Make the Biggest Difference
Brush Twice Daily
Use fluoride toothpaste and brush for two minutes, morning and before bed.
Floss Every Day
Flossing removes decay-causing bacteria from between teeth where brushes can't reach.
Drink Fluoridated Water
Perth tap water is fluoridated, drinking it throughout the day helps protect your teeth.
Limit Sugar & Acid
Reduce sugary snacks and acidic drinks. When you do consume them, rinse with water afterwards.
Never Skip Night Brushing
Saliva flow drops during sleep, making night the highest-risk time for decay. Always brush before bed.
Regular Dental Visits
Professional monitoring catches problems early when they're quick and inexpensive to fix.
Frequently Asked Questions
How often should I have a check-up to prevent cavities?
Every six to twelve months. Patients at higher decay risk benefit from more frequent monitoring. Your dentist will advise the right schedule for you.
Are fissure sealants worth it for my child?
Yes, they're very effective. Back teeth have deep grooves where food traps and bacteria thrive. Sealants physically block these grooves and can prevent cavities for years.
Can a cavity heal on its own?
Very early enamel damage can remineralise with fluoride, but once a cavity forms, it won't reverse. Early treatment is essential to prevent it spreading to deeper layers.
Why do I get more cavities than other people?
Genetics, saliva chemistry, diet, oral hygiene habits and certain medications all affect decay risk. A risk assessment helps us understand your individual situation and tailor prevention.
Does fluoride really work?
Yes, fluoride is one of the most well-researched public health interventions in history. It strengthens enamel and reduces cavity rates significantly across all age groups.
