How to Maintain a Philips Sonicare Toothbrush

Daily rinse and air dry

The core of any Sonicare maintenance routine is the same as general toothbrush care: rinse the brush thoroughly after each use to remove remaining paste and debris. That applies to both the handle and the brush head. Shake off excess water and place the handle upright in a spot where air can move around it. The American Dental Association recommends allowing the toothbrush to air dry rather than storing it in a closed container.

If you store several toothbrushes together, keep them separated to prevent cross contamination. The ADA also advises against sharing toothbrushes, since sharing can exchange bodily fluids and microorganisms. For a family, use separate brush heads and handles, or at least separate heads. You can also review the family toothbrush guide to see how a shared routine can stay hygienic.

• Rinse the handle and brush head under tap water
• Shake off excess water before storing
• Store the handle upright and uncovered
• Keep multiple brushes separated

Replace brush heads on schedule

The most important maintenance step is replacing the brush head. The ADA says toothbrushes should be replaced every three to four months, or more often if the bristles become matted or frayed. The same rule applies to a Sonicare brush head. As bristles wear, the brush becomes less effective at cleaning. Check the bristles each time you brush and replace the head when they start to look bent, splayed, or worn.

Use a brush head designed for your handle. Not every head fits every Sonicare, so check compatibility before buying replacements. If your model includes a replacement reminder, treat it as a helpful signal, but still inspect the bristles. If you are unsure which head family you need, see the guide to Philips Sonicare brush head types.

Do not share brush heads between people. Even with a shared handle, each person should have their own head and the handle should be wiped clean before handing it over. The ADA notes that sharing a toothbrush can exchange bodily fluids and microorganisms.

Keep the charger and contacts clean

The charger needs less attention, but it still deserves a place in your routine. Keep the charging stand or glass free of toothpaste residue and dust. A dry cloth is usually enough to clean the charging contacts. If the charger is plugged in, unplug it before wiping the contacts. Do not immerse the charger in water unless the manufacturer's instructions for that accessory say it is safe.

A Sonicare charging glass can collect toothpaste spit and hard-water film over time. Rinse the glass and let it dry before returning the handle. Keeping the charging area clean also helps the handle sit correctly and avoids residue building up around the base. If you are shopping for a new model, the guide to the best Philips toothbrushes can help you compare charging styles.

Let travel cases breathe

Travel cases protect a Sonicare in a bag, but they can create the same damp environment as any closed container. The ADA explains that storing a moist toothbrush in a closed container promotes microbial growth more than leaving it exposed to open air. So before sealing a travel case, give the handle and brush head time to dry. If you are on the road, shake off excess water and leave the case open when you can.

Some Sonicare cases are designed for charging while traveling. If yours has a charging port or cable, keep the opening clean and dry. If the model has a travel lock to stop the handle from turning on inside the case, use it so the motor does not run against the case. For more tips, see the travel case cleaning guide and the general guide to caring for a toothbrush while traveling.

Avoid damaging shortcuts

Do not microwave a Sonicare brush head or put it in the dishwasher. The ADA says microwaving or putting toothbrushes in the dishwasher is not recommended because high heat may damage the brush. That advice applies to the handle as well. If you want to sanitize a brush head, one study cited by the ADA found that soaking a toothbrush in 3 percent hydrogen peroxide or an antiseptic mouthwash greatly reduced bacterial load. Follow any product instructions, and remember that rinsing and air drying is the first line of defense.

Do not routinely store the brush under a cover or in a closed container. If you use a cover, let the brush dry first. The ADA says a moist environment is more conducive to unwanted bacteria than open air.

Questions

How often should I replace my Philips Sonicare brush head?

Replace it every three to four months, or sooner if the bristles look matted or frayed. The ADA recommends this interval because worn bristles are less effective at cleaning. See the guide to replacing toothbrush heads.

Can I soak my Sonicare handle in water to clean it?

Rinsing is safer than soaking. The handle and brush head should be rinsed after use and allowed to air dry. Avoid immersing the charger in water. If you need to sanitize a brush head, the ADA notes that soaking in 3 percent hydrogen peroxide or mouthwash greatly reduces bacterial load, but do not put the brush in the dishwasher or microwave.

Is it okay to keep my Sonicare in a travel case after every use?

No, not while it is wet. A closed container creates a moist environment that promotes microbial growth. Let the brush air dry before closing the case, and clean the case periodically. For more detail, see the travel case cleaning guide.

Can I put my Sonicare brush head in the dishwasher?

The ADA does not recommend microwaving or dishwashing toothbrushes because high heat may damage the brush. Follow the same caution for the handle and brush head.

Should I share a Sonicare handle with my partner?

The ADA advises against sharing toothbrushes. Sharing can exchange bodily fluids and microorganisms. If you do share a handle, each person should use their own brush head and the handle should be cleaned before switching.
