Dentist Reveals 4 Common Toothbrushing Mistakes That May Damage Teeth and Gums

We all brush our teeth every day, but most of us are actually brushing them wrong and do not know it. Some of our most common morning and nighttime habits can slowly chip away at enamel, recede gums and cause painful tooth sensitivity over time, dentists warn.

Have a healthy smile: Here are 4 common brushing mistakes you need to stop making today.

1. Scrubbing Like You’re At The Kitchen Sink

It’s tempting to think the more you scrub, the cleaner your teeth become. But your teeth aren't a countertop. It’s like sanding your teeth. Brushing too hard wears away your protective enamel and irritates your gums. Instead, use gentle circular motions to dislodge plaque without damaging it.

2. Stick with the Wrong (or Old) Brush

A toothbrush with hard bristles can actually do more harm than good. Hard bristles can cut into the gum tissue and wear away the enamel. Use a brush with soft bristles. “Gentle on plaque. Hard on your mouth.” Also, remember to throw away your toothbrush and get a new one every 3-4 months.

3. Brushing Immediately After a Meal

It’s natural to brush your teeth after a meal, but if you’ve just had coffee, soda or citrus fruit, you’re actually brushing acid right onto your teeth. The acid temporarily softens your enamel, and brushing while it’s in this weakened state speeds up erosion. Wait at least 30 minutes before you brush, letting your saliva naturally neutralise the acid.

4. Leaving Your Job Way Too Soon

Everyone thinks they brush for a long time, but the average person gets about 45 seconds. Your dentist tells you to brush for two minutes, twice a day. If you make it shorter, you will miss a lot of plaque on the hard-to-reach surfaces of your teeth.

The Bigger Picture Oral health isn’t just about preventing cavities or having fresh breath. Poor oral health has been linked to many health conditions, including heart disease and diabetes. Your whole body will thank you for the extra minute to brush well, regular flossing and dental check-ups.
