A whiter smile could be as easy as throwing out your old toothbrush. According Dr. Glosman, “Replace a toothbrush every three months, or as soon as you see the majority of the bristles begin to bend and look worn down.” After the bristles are worn down, your toothbrush isn’t cleaning your teeth properly.
Brush your tongue
Brushing your tongue isn’t only about having fresh breath. Dr. Glassman says it can also help prevent staining. Your tongue accumulates bacteria, which can eventually lead to discoloration. Use a soft toothbrush and long strokes starting at the very back of the tongue, rinsing your brush after each stroke. This will help remove the bacteria on the brush without re-depositing it on your tongue.
Rinse with apple cider vinegar
While it isn’t as effective as other, more mainstream whitening treatments, it is a natural and organic way to maintain a healthy smile. Dr. Glassman recommends rinsing with two parts water to one part apple cider vinegar, and swishing the solution around for one minute.
Eat raw fruits and veggies
Eating fruits, vegetables, and other crunchy foods is good for your body and your teeth. Dr. Glosman says that eating nuts, raw carrots, apples, and cauliflower can help keep your teeth clean by removing surface stains and plaque that leads to cavities.
Use gel trays instead of strips
Experts are divided on the effectiveness of whitening strips. Dr. Glassman says she’s not a fan of strips because they don’t distribute the whitening paste evenly. Teeth are usually darkest near the gum line, where the strips can’t reach. Instead, she recommends using whitening gel trays.
Rinse with water after eating oranges
Although they’re a good go-to for vitamin C, citrus fruits, such as lemons and limes, contain acid that erodes tooth enamel. This can make teeth stain more easily. The fix? Make sure to rinse your mouth out with water immediately after eating these fruits to wash the destructive acid off your teeth.
