Teeth can decay at any age, starting as soon as the first tooth appears (around 6-10 months), with early childhood caries (ECC) being common in toddlers (28% of 2-5 year olds have cavities). While decay in baby teeth is prevalent in children (over 40% by age 10), it also affects adults, with rates increasing with age, impacting permanent teeth as well.
The American Dental Association says that some children experience tooth decay at just 6 months old. At Kids Dental Center in Greenbelt, Maryland, our kid-friendly pediatric dentist Bosede Adeniji, DDS, and caring team of specialists understand the oral health needs of young patients.
The 2-2-2 rule in dentistry is a simple guideline for good oral hygiene: brush twice a day, for two minutes each time, and visit your dentist twice a year, helping to prevent cavities, gum disease, and other dental problems by establishing consistent habits for plaque removal and professional monitoring.
Symptoms
Research shows that 90% of people between the ages of 20 and 64 have had at least one cavity, and the prevalence of cavities increases with age. Developing a cavity, or even two, between six-month checkups isn't alarming.
A handful of fillings at 30 is normal. But if you've had 8–10 or more cavity fillings by age 30, it could be a sign of high cavity risk. That doesn't mean your teeth are unhealthy—it just means tooth decay prevention should be a bigger focus going forward.
Using a mouthwash that contains fluoride can help prevent tooth decay. But don't use mouthwash (even a fluoride one) straight after brushing your teeth because it will wash away the concentrated fluoride in the toothpaste left on your teeth. Choose a different time to use mouthwash, such as after lunch.
The "333 dental rule" refers to two different concepts: a hygiene guideline (brush 3 times a day for 3 minutes, replace brush every 3 months) and a temporary toothache relief method (take 3 ibuprofen tablets, 3 times a day, for 3 days). The hygiene rule promotes better habits, while the pain management rule helps control inflammation and pain before a dental visit, but requires caution as it's not a cure.

When you eat sugary foods or sip sugary drinks for long periods of time, plaque bacteria use that sugar to produce acids that attack your enamel, the hard surface of your tooth. Most carbonated soft drinks, including diet soda, are acidic and therefore, bad for your teeth.
If you have dry mouth—whether from genetics, medications, or stress—you're at higher risk for cavities. So when someone says, “I never brush my teeth and have no cavities,” they might simply have protective, high-quality saliva that naturally balances their oral ecosystem.
Yes, dentists can often tell if you only brush once a day. Signs like plaque buildup, gum inflammation, and tartar reveal brushing frequency during exams.
So, how often should you floss? It's an easy question to answer: daily. When you're flossing once per day, try to ensure your technique is effective at removing plaque between your teeth and below the gumline.
Between the ages of 50 to 64, you have about a 10% chance of having no teeth remaining at all, and this number jumps up to 13% when you get to age 74. Once past the age of 74, the number jumps even higher to 26%.
A dentist can prescribe fluoride treatments like mouthwash or varnish to reverse early tooth decay. You'll probably need a filling if you have a hole (cavity) in your tooth.
Upper canines and second molars – The last baby teeth to fall out, typically between ages 10-13.
Studies show that electric toothbrushes do a better job of cleaning your teeth than manual toothbrushes do, which can help prevent cavities and gum disease.

Within minutes of skipping brushing, bacteria in your mouth start feeding on leftover food. This creates plaque, a sticky film that coats your teeth. After a few hours, plaque starts producing acid that weakens enamel.
Code 1 – Slight bleeding when probed, no calculus or gingival pockets under 3.5mm. Code 2 – Slight bleeding when probed, Calculus or Plaque present and gingival pockets under 3.5mm. Code 3 – Calculus and Plaque present under the gum margin and gingival pockets between 3.5 – 5.5mm.
The golden rule for oral hygiene encompasses a consistent and comprehensive approach to dental care. You can ensure a healthy and beautiful smile by brushing twice daily, flossing daily, using mouthwash, maintaining a nutritious diet, staying hydrated, avoiding tobacco, and visiting your dentist regularly.
Once you've brushed, don't rinse your mouth with water or mouthwash -- you're washing away the fluoride! This can be a difficult habit to break, but can reduce tooth decay by up to 25%.
As long as flossing is done thoroughly, the practice can reach locations below the gumline that brushing is unable to reach; therefore, flossing is seen to be effective before and after brushing, according to the ADA.
Oral health professionals often recommend patients use saltwater when a wound or infection is present in the mouth. Saltwater can even destroy bacteria that leads to the formation of cavities. Swish with salt water as soon as you find out you have a cavity and it just might slow its expansion.
