Cavities often come back in your teeth, and when they come back, it not always come on the same area, and this happens to everyone. Molars are the kind of large teeth at the back of your mouth, just like magnets.
Molars are important because they play a heavy role, like when you chew, and their shape is more vulnerable to food, plaque, and bacteria. Understanding the importance of the first step of teeth protection will help in the long run.
The Hard-to-Reach Areas Causing Plaque Build-Up
Back teeth are the areas where it are quite difficult to reach, which results in plaque building. Because back teeth have grooves, pits, and fissures for chewing. These tiny hidden spots also cause bacteria and food debris.
And with that, Molars sit quite back in the mouth, which is comparatively more difficult to reach. And due to the busy schedule, people unintentionally miss that to brush. And over time, plaque becomes more harden into forms tartar, which increases the risk of cavities.
And brushing the misaligned molars makes it more difficult to clean, which allows the accumulation between the teeth, and due to that, flossing becomes more effective.
How Chewing Habits Impact Cavity Formation
Chewing food while eating is important, and it plays a bigger role than anyone thinks. Molars are designed to chew, and due to that, they’re constantly exposed to sugars and starches. Foods that are sticky, like caramel, dried fruit, chips, and bread which get stuck in the back teeth.
And having frequent snacks keeps the acid levels high in the mouth. And whenever someone eats something, the mouth is left with bacteria that release the acids, resulting in weakened enamel.
Chewing on one side of the mouth more than the other can also create uneven wear and plaque build-up, making certain molars more cavity-prone than others.
Preventive Steps for Molar Care
The good news is that cavities in back teeth are largely preventable with the right care and habits.
Brush your teeth with a dentist-proven technique
Use a small-headed or soft toothbrush and angle it slightly to reach the grooves of your molars. It takes some time, but it removes all the bacteria back and forth.
Floss daily, especially the back teeth
Cavities often start between molars and back teeth, where toothbrushes can’t reach. Flossing daily, especially in the back teeth, removes plaque before it hardens the tartar.
Consider fluoride and sealants
Fluoride strengthens enamel in Molars and prevents early cavities. Dental sealants, often recommended by a Dentist Specialist in Sydney, protect the molars' deep grooves barrier which are mostly prone to children and cavity-prone teeth in adults.
Watch your diet
Limit sugary snacks and acidic drinks daily. Rinse your mouth very deeply and take some time too, but do so after having a meal.
Regular dental check-ups
Dentists remove the hardened plaque in Molars, which helps to detect it early before it becomes painful or costly to treat.
