Do You Really Need an Expensive Electric Toothbrush? What Dentists Think in 2026
AI-powered toothbrushes are becoming increasingly popular, but do you really need to spend hundreds of pounds on an electric toothbrush?
With new AI toothbrushes and smart electric toothbrushes now using cameras, sensors and machine learning to analyse your brushing, dental technology is becoming more sophisticated than ever.
But here's the important question:
Does a more expensive toothbrush actually mean healthier teeth and gums?
The answer is not necessarily.
What is an AI toothbrush?
An AI toothbrush is a smart electric toothbrush that can monitor your brushing and provide feedback.
Depending on the model, features can include:
Detecting areas you may be missing.
Monitoring how long you brush.
Detecting excessive brushing pressure.
Tracking your brushing habits.
Providing personalised feedback through an app.
These features can be useful, particularly if you struggle with brushing technique or regularly miss certain areas.
Do you need an expensive electric toothbrush?
No.
For most people, the fundamentals of good oral hygiene remain much more important than the price of their toothbrush.
The key recommendations are simple:
Brush your teeth twice a day with fluoride toothpaste.
Clean between your teeth every day.
Avoid brushing too aggressively.
Limit frequent sugary food and drinks.
Attend regular dental check-ups.
An electric toothbrush can make brushing easier and features such as a two-minute timer and pressure sensor can be genuinely useful.
However, spending £400 on a toothbrush doesn't automatically make it better at looking after your teeth.
Is an electric toothbrush better than a manual toothbrush?
Both can be effective when used correctly.
An electric toothbrush can be particularly helpful if you:
Brush too hard.
Struggle with brushing technique.
Find it difficult to brush for long enough.
Have braces or other dental appliances.
Regularly miss areas of your mouth.
Ultimately, the best toothbrush is one that you use correctly and consistently.
What is most important for healthy gums?
Your toothbrush is only part of the picture.
Plaque left around and between your teeth can contribute to gum disease, which can cause bleeding, swelling, bad breath and, if left untreated, potentially tooth loss.
This is why daily interdental cleaning is so important.
Your dentist or hygienist can also show you where you are missing plaque and recommend the right toothbrush, toothpaste and interdental products for your individual needs.
The bottom line
AI toothbrushes are an exciting development in dental technology and their feedback could help some people improve their brushing.
But you don't need an expensive electric toothbrush to have healthy teeth and gums.
Good technique, consistency, fluoride toothpaste and cleaning between your teeth will usually matter far more than how much you spend on your toothbrush.
Sometimes the best upgrade isn't a more expensive toothbrush.
It's better technique.
Frequently Asked Questions
Is an expensive electric toothbrush worth it?
It can be useful if you will benefit from features such as pressure sensors, timers or personalised brushing feedback. However, it isn't essential for good oral health.
What is the best electric toothbrush for gum health?
There isn't one toothbrush that is best for everyone. A pressure sensor can be particularly useful if you tend to brush too hard, while professional advice can help you choose the right toothbrush for your needs.
Is an AI toothbrush better than a normal electric toothbrush?
Not necessarily. AI can provide additional feedback, but effective brushing technique and consistent oral hygiene remain more important.
How often should I brush my teeth?
For most people, brushing twice a day with fluoride toothpaste is recommended.
Do I still need to see a dentist if I have an AI toothbrush?
Yes. An AI toothbrush cannot replace a dental examination or professional assessment of your teeth and gums.
