Toddler Toothbrush: What to Look For

Start with size and softness

For a toddler, the two features that matter most are a small head and soft bristles. The American Dental Association recommends using a child-sized toothbrush with a head small enough to move easily inside the child's mouth and reach all tooth surfaces. Small heads also feel less overwhelming for a young child, which can make brushing easier.

Soft bristles are the standard recommendation for children and adults. Firm or medium bristles can cause damage to gums and enamel. For toddlers, who may press down or chew on the brush, soft bristles are especially important.

If you are comparing a toddler brush with an adult brush, see kids vs adult toothbrush for the main differences.

Head shape and size

Look for a compact head, not a long one. A toddler's mouth is much smaller than an adult's, and the back teeth are still coming in. A brush with a rounded or smaller head is easier to angle toward the gumline and back molars. Some toddler brushes are labeled by age range, but it is still worth checking the head size visually. It should look small compared with the child's front teeth.

Head shape can be round or rectangular, but shape is less important than size. Choose one that lets you reach the inside, outside and chewing surfaces. For more on head shapes, see round vs rectangular head and toothbrush head size.

Bristle firmness

Choose soft bristles. The ADA specifically recommends soft bristles because they minimize the risk of gingival abrasion. Even a brush labeled soft can vary, so look for bristles that feel gentle when you run a finger across them. If your child has sensitive gums, an extra-soft option may be more comfortable. Bristle firmness meaning explains the labels.

Also check that the bristles have rounded ends. Many brushes advertise this, and it helps reduce irritation. End-rounded bristles has more detail. A brush with the ADA Seal has met the ADA's safety and efficacy requirements, including bristle retention and handle strength.

Handle size and grip

A toddler does not have the manual coordination to brush effectively alone, so the handle matters in two ways. First, an adult needs to hold it while brushing the child's teeth. Second, the toddler may want to practice holding it. A handle that is too thick or too thin can be hard for small hands to grip. Look for a handle with a comfortable non-slip grip.

Some toddler brushes have larger, chunky handles that are easier for a child to grasp. Others have a slim handle that works best when an adult is doing the brushing. Consider how you will use the brush. If your child insists on holding it, a chunky handle may help them feel involved while you guide their hand. Toothbrush handle design compares common handle styles.

Manual or powered toothbrush

Both manual and powered toothbrushes can clean a toddler's teeth effectively. The ADA and the NHS both say that the type of brush matters less than brushing twice a day with fluoride toothpaste and cleaning all tooth surfaces. Some children accept powered brushes more easily because the vibration feels interesting, while others prefer a simple manual brush.

If you choose a powered brush, pick one designed for children with a small brush head and soft bristles. It should also have a gentle mode if possible. For more on the main options, see manual vs electric toothbrush and battery vs rechargeable kids toothbrush.

If your toddler is sensitive to noise or vibration, a manual brush may be easier at first. Electric toothbrush noise discusses what to expect.

Fluoride toothpaste and how much to use

Tooth decay can start as soon as teeth appear, and young children are at risk for early childhood caries. Brushing with fluoride toothpaste helps prevent this. For children under age 3, use a smear of fluoridated toothpaste about the size of a grain of rice. Once your child is 3 or older, a pea-sized amount is appropriate. Have your child spit out the excess after brushing.

Children do not need special children's toothpaste. According to the NHS, children of all ages can use family toothpaste with 1,350 to 1,500 ppm fluoride. Children under 3 who do not have tooth decay may use a lower-strength children's toothpaste, but it should contain at least 1,000 ppm fluoride. Ask your dentist if you are unsure which strength to use.

Replacement and daily care

Replace your toddler's toothbrush every three to four months, or sooner if the bristles look matted or frayed. A worn brush does not clean as well and can be rougher on gums. After each use, rinse the brush, store it upright and let it air dry. Do not store it in a closed container while it is wet.

Toothbrushes should not be shared. Keep your child's brush separate from other brushes to avoid cross contamination. If the brush has a suction cup or stand, make sure it does not trap water around the bristles. How to dry and store toothbrush has more tips.

What to pick for your toddler

Start with a child-sized manual brush with soft bristles and a small head. If your toddler refuses to open up, a powered brush with a small head and a timer may make the routine more engaging. An ADA Seal on the package tells you the brush met the ADA's requirements for safety and efficacy.

Whichever brush you choose, the most important part is adult help or supervision. Children need help brushing until they are at least 7 years old. For toddlers, an adult should do the brushing or guide the child's hand. Use the two-minute timer meaning to keep brushing sessions long enough.
