Dental cavities are a common dental problem that affects millions of people worldwide. The problem with cavities is that they tend to be painful and can lead to other dental complications if not treated in time. As mentioned earlier, cavities are caused by bacteria in your mouth that feed on food particles and produce acid as a byproduct. This acid, in turn, erodes tooth enamel and leads to cavities.

It’s worth noting that the bacteria that cause cavities are highly contagious and can spread from one person to another via various means. For instance, sharing utensils or drinking from the same bottle as someone with cavities can increase your risk of contracting the bacteria.

Practice good dental hygiene to prevent the spread of cavity-causing germs. Good dental hygiene includes:

* Brushing your teeth twice a day.
* Flossing regularly.
* Avoiding sugary and acidic foods.

Additionally, it would help if you visited your dentist regularly for checkups and dental cleanings to keep your teeth healthy and free from cavities.

In conclusion, dental cavities are caused by sugary foods and bacteria that can spread from person to person. Practicing good oral hygiene and visiting your dentist regularly to prevent the spread of these germs is essential.
