Philips Sonicare DiamondClean electric sonic toothbrush: models, features and buying tips

A Philips Sonicare DiamondClean electric sonic toothbrush is designed for adults who expect more than a basic electric toothbrush. App support, several cleaning modes, pressure control and a travel case can make everyday use easier. However, it’s worth checking the model number, what’s included and the ongoing costs before you buy.

Common pitfalls when buying a smart sonic toothbrush

1. More modes don’t automatically mean a better experience

A large number of cleaning modes may sound impressive at first. What matters, though, is whether you’ll actually use them day to day and whether you can adjust the intensity. If you have sensitive gums, you may mainly need a low intensity setting and clear pressure feedback.

Depending on the model, DiamondClean toothbrushes combine several modes with three intensity settings. The Philips Sonicare DiamondClean 8500 has six modes, giving you 18 combinations. The Philips Sonicare DiamondClean 9000 has seven modes and 21 combinations.

2. App features don’t replace good brushing technique

A sonic toothbrush with an app can show you how long you’ve brushed, which areas you’ve covered and how much pressure you’re applying. However, your phone needs to be connected, charged and within range. If you don’t want to use an app, check that the toothbrush is still easy to use on its own.

The DiamondClean models mentioned here also have a timer, a 30-second pacing reminder and an interactive display. These features work directly on the toothbrush, so they don’t rely solely on the app.

3. It’s easy to overlook what’s included

With a premium toothbrush, a charging glass, travel case and spare brush heads can make a real difference to its practical value. A lower price is less appealing if you later have to buy a compatible charging case or extra brush heads separately.

Each of the models featured here comes with an A3 Premium All-in-One brush head, a charging glass and a travel case with charging function. Even so, check the colour, model number and what’s included on the product page before you buy.

What to check before you buy

Cleaning modes and intensity settings

When choosing an electric toothbrush for adults, the advertised number of brush movements per minute isn’t the only thing to consider. It’s more important to check whether the toothbrush suits different everyday needs. The DiamondClean 8500 HX8513/12 and HX8513/11 have Clean, Deep Clean, White, Gum Health, Sensitive and Max Care modes. With three intensity settings, that gives you 18 settings to choose from.

The DiamondClean 9000 HX9213/84 and HX9213/85 have seven modes and three intensity settings, giving you 21 combinations. More choice is only useful if you regularly adjust the mode and intensity to suit your own habits.

Pressure sensor and feedback

A toothbrush with a pressure sensor should make it easy to understand when you need to adjust how firmly you’re brushing. On the DiamondClean models mentioned here, a coloured ring indicates the pressure: according to the product description, green means the pressure is right, a pulsing purple light means it’s too high, and a slow purple light indicates that it’s too low.

This feedback can help you brush more mindfully, but it isn’t a medical assessment. If you have pain or bleeding gums, or you’ve recently had dental treatment, it’s a good idea to speak to your dental practice.

Battery life and travel options

A toothbrush with 14 days of battery life is handy for commuting, business trips and holidays. The stated battery life of up to 14 days depends on how you use it, its charge level and operating conditions. Charging takes around 24 hours.

The DiamondClean travel case does more than store the toothbrush: it can also charge the handle. If you travel frequently, check the mains voltage too. The product information specifies a range of 100 to 240 volts. The charging glass and travel case must not get wet or be immersed in water.

Brush head and ongoing costs

The A3 Premium All-in-One brush head is designed to provide a thorough clean. The BrushSync feature reminds you when it’s time to replace it. According to the product description, replacement is typically recommended after around three months, or sooner if the brush head shows visible signs of wear.

Before you buy, check which replacement brush heads are available and how many people will be using the handle. If several people will use it, you’ll need additional brush heads. The different modes may also affect power consumption, but in everyday use, the ongoing cost of replacement brush heads is usually the more significant expense.
