Poor oral hygiene can lead to gum disease and tooth loss, but it can also affect the rest of the body in ways many people do not expect.
Experts note that failing to care for your teeth and gums may raise the risk of conditions like cardiovascular disease and even stroke, making regular brushing important for overall health.
The clip shows what the creator claims are different stages of plaque buildup, starting with a thin, nearly invisible layer forming on the teeth after just one day.
By day three, the video suggests thicker clumps of plaque begin to collect between teeth, making the buildup more noticeable.

The dramatic visuals raise an obvious question about how realistic the simulation really is.
The creator labeled the video as AI-generated, which means the exact images should not be taken as a medical prediction.
Still, dental professionals agree that skipping brushing for extended periods can cause serious and lasting damage.
Dental treatment for these problems can also be costly, often far more expensive than maintaining a simple daily routine with a toothbrush and toothpaste.
Diet plays a role as well, since frequent sugary foods and drinks can weaken enamel and speed up tooth damage.
Regular dental checkups remain essential for catching problems early before they become severe.
Healthline advises: “It’s tough to fully predict what would happen if you didn’t brush your teeth for a year.”
