Wondering why your pearly whites aren’t so pearly anymore? Yellowing teeth can result from genetics, aging, or everyday habits like smoking and drinking coffee. While some factors, like enamel thickness or medical treatments, are out of your control, many causes are preventable with better oral care.

Genetics can mean thinner enamel or more porous teeth, making stains set in faster. Aging wears down enamel, exposing yellow dentin. Smoking, poor hygiene, and certain medications also contribute to discoloration. Medical conditions like acid reflux or liver disease can weaken enamel or cause deep stains.

To keep your smile bright, brush with fluoride toothpaste, floss daily, avoid stain-heavy foods, and get regular cleanings. Quit smoking and stay hydrated, especially if medications or illness cause dry mouth. When stains persist, professional whitening or veneers may help.

Good oral hygiene and smart habits go a long way in keeping your teeth whiter, healthier, and ready to flash that confident smile.
