Are you unknowingly damaging your teeth? A dentist reveals the four frequent brushing mistakes you're probably making!

Good dental health goes way beyond brushing your teeth twice a day and not eating too much sugar.

In reality, there are so many factors that can potentially damage your teeth and gums, and if you're not aware of them, it could lead to serious issues in the future.


Dentists have come to our aid and shared their top tips and tricks that would help keep our pearly whites in tip-top condition.

1: Using mouthwash after brushing

Many of us are probably in the habit of rinsing our mouths with water or mouthwash after brushing our teeth.

However, Dr Praveen Sharma, a Birmingham-based Specialist in Restorative Dentistry and Scientific Adviser to the British Dental Association, said that rinsing your mouth out with mouthwash after brushing your teeth can actually remove the fluoride residue from your toothpaste, which is what helps protect your teeth from harmful bacteria and reduces your risk of cavities by 25 per cent.

Instead, your best bet is to simply spit after brushing and using mouthwash at a different time.

'After brushing, spit don't rinse, or you'll dilute the benefit of fluoride,' Dr Sharma advised.

'If you use mouthwash, the same principle applies, make sure to use [them] at different [times]...'


2: Not allowing enough time between eating and brushing

For sparkly smiles and good dental hygiene, experts suggest waiting at least 60 minutes before cleaning your teeth after meals.

This is because the enamel on your teeth needs time to remineralise naturally, especially after eating or drinking something acidic (like a soft drink).

Dr Sharma said: 'Ideally, leave a gap of between 30-60 minutes after eating or drinking before brushing your teeth because the mouth needs a little time to clean itself and let the surfaces of the teeth reset.'

'You might think that ''diet'' soft drinks, fruit juices and smoothies are safe alternatives, but they aren't. There's an acid component to many of them which attacks the surface of your teeth, raising the risk of erosion—wearing away the surface of the teeth—and tooth decay.'

Tooth decay is a result of a sticky layer of bacteria buildup called plaque, which damages the surface of the teeth over time.


3: Not using interdental brushes


If you're not already using interdental brushes, then you're probably putting your teeth and gums at risk.

These small tools can help get into the gaps of your teeth where pieces of food and plaque can build up, causing gum disease if not removed.

'Aim to clean the spaces in between your teeth (where there is space) with interdental brushes at least once a day,' suggested Dr Sharma.

'It is advisable to do this before brushing. If the spaces between the teeth are too tight to insert a brush, use floss.'

'When brushing, aim the bristles of the brush down towards the gum for the bottom teeth and up towards the gum for the top teeth at 45 degrees.

'This allows the bristles to go slightly below the gum line.'

Dr Sharma recommends brushing in small circular motions and avoiding a 'scrubbing motion' which can damage one’s teeth and gums.


4: Not brushing your teeth before bed

Not brushing your teeth at night allows bacteria to feast on sugars from food and mouth acids in the absence of saliva defences, which is lower when one is asleep.

'Saliva helps to wash away the bacteria that cause tooth decay,' Dr Sharma explained.

'Brush teeth twice daily with a fluoride toothpaste for at least two minutes to thoroughly clean all the surfaces of your teeth, especially before going to bed when saliva production is at its lowest.'


Another area of dental health that often gets overlooked is the care of dentures.

Like natural teeth, dentures also require daily cleaning. Not only will this keep them sparkling, just like your original set, but it can also enhance their lifespan.

It is recommended to run a soft-bristle toothbrush over your dentures at least twice a day.

Moreover, instead of common toothpaste, use a mild dishwashing liquid or denture cleaning solution, because many toothpastes are abrasive and might cause small damages over time.

In addition, wearing your dentures continuously without giving them a break can lead to discomfort and other oral issues.

So, remember to soak your dentures in water or a denture-cleaning solution overnight. This helps to keep them moist and retain their shape.

Ensuring proper care of your dentures is crucial for overall oral health and can help you to avoid unnecessary discomfort or denture repairs. So, just as with regular teeth, don’t neglect your faux pearly whites. They deserve some love too!
Key Takeaways
  • Dentists recommend waiting up to 60 minutes after eating before brushing your teeth to prevent enamel damage.
  • Using mouthwash or rinsing immediately after brushing can remove beneficial fluoride residue from your teeth.
  • It is advised to clean between your teeth using interdental brushes or floss at least once a day, ideally before brushing.
  • Not brushing before bed can allow bacteria to damage your teeth as saliva production, which helps wash away bacteria, is at its lowest during sleep.

I’m sure by the time we reach our senior years we have all mastered brushing and looking after our dental hygiene.
 
I used to brush right after meals, thinking I was doing the right thing, but my General Dentist in Eastlake Ohio told me that doing that—especially after acidic foods—can actually wear down enamel. I also switched to a softer toothbrush and stopped scrubbing so hard. It’s crazy how just changing a few small habits made my teeth feel less sensitive.

A Dentist Reveals 4 Common Brushing Mistakes You Might Be Making!​


Brushing your teeth is a daily habit — but what if you're doing it wrong and unknowingly harming your enamel, gums, and overall oral health?


A top dentist reveals 4 frequent brushing mistakes that many people make without realizing it — and how to fix them before they lead to tooth damage.




Mistake #1: Brushing Too Hard​


The problem: Scrubbing with force doesn’t clean better — it wears down your enamel and irritates your gums.


The fix: Use gentle, circular motions with a soft-bristled toothbrush. Let the bristles do the work, not your wrist.


Pro Tip: If your brush bristles look flattened or frayed, you're brushing too aggressively.




Mistake #2: Not Brushing Long Enough​


The problem: Many people brush for less than a minute — that’s not enough to clean all surfaces.


The fix: Brush for 2 full minutes, twice a day. Use a timer or electric toothbrush with a built-in alert.


Each section of your mouth (top right, top left, bottom right, bottom left) should get 30 seconds of attention.




Mistake #3: Using the Wrong Toothbrush​


The problem: Hard-bristled brushes or oversized heads can cause damage and miss spots.


The fix: Use a soft-bristled toothbrush that fits your mouth comfortably. Consider switching to an ADA-approved electric brush for deeper cleaning and better plaque removal.


Avoid cheap or unbranded brushes — your dental health is worth investing in.
 
One thing that really helped me was switching to a soft-bristle brush and being more mindful about not brushing too hard—my gums used to bleed sometimes, and that totally stopped. Also, using interdental brushes made a huge difference for me, especially for stuff floss used to miss.
