If you start brushing without charging the device, you'll hear 3 audible beeps to remind you that there's only limited power available. The cleaning may also be less forceful as the battery runs down.

Replacement brush heads are easily interchanged between electric toothbrush handles.

There may be a few exceptions, especially involving the much older Sonicare models which had brush heads that required to be screwed on instead of snapping into place. Such models can only be used with a more restricted range of replacement heads.

But other than these rare exceptions, all other models can be mixed and matched without any trouble.

Gum infection or gingivitis and the build up of dental plaque go together. Oral health worsens when there is a gum infection. Sticky and thick dental plaque collects more often where an infection is established. Over time, this leads to damage to teeth causing them to fall out.

Periodontal disease affects the gums and jaw along with teeth. It gets worse whenever there is collection of dental plaque. Gums become painful when touched or brushed when there is gingivitis.

Drawbacks

Limited value of app data: Although the app features prominently in any Philips Sonicare DiamondClean review, the data it collects and the insights it offers are usually disappointingly limited.

Cost: As one of the more expensive electric toothbrushes on the market, the cost is a major deal breaker for some potential buyers. It helps to look at how much value you'll get for your money before making a decision.

If charge drops very low and the device is due for a recharge, the color of this light changes to amber and it continues flashing.
