Meta description

We have different designs of modern-day toothbrushes, and each reveals a particular dental need in maintaining oral hygiene.

Toothbrushes typically consist of the head, the handle, and the shank. We have toothbrushes available in different designs. Each design is made to meet specific dental demands. The manual and electric toothbrushes offer different bristle head sizes and handle configuration choices. Each has its advantages and disadvantages. Manual toothbrushes can give the perfect job of cleaning your teeth. Electric toothbrushes are new designs that are easier to use and more effective for your needs. It performs the actual brushing motion for you. It is a good choice for people with arthritis or other manual dexterity.

Each design is made to meet the demands of the mouth. For example, a person with a larger mouth can accommodate a larger toothbrush head, even though a smaller head is more effective for brushing the back molars. Toothbrush designs are based on the bristles type, the head size, the bristles pattern and the handle design.

Toothbrush designs  based on bristle types

  • Soft bristles toothbrush

Toothbrushes with soft bristles are less aggressive for tooth enamel and gums. For this reason, they are particularly recommended for people suffering from gum or tooth sensitivity. On the other hand, the soft bristles can reach the interdental spaces without difficulty, thus guaranteeing complete oral hygiene. Dentists usually recommend using soft-bristled toothbrushes for all their patients, as they are very effective and do not attack the teeth and gums.

  • Medium-bristled toothbrushes

Toothbrushes with “medium” bristles are the most popular and best-selling. If you do not have any particular problems with your teeth and gums, you can use them safely.

However, if you experience bleeding or gum pain after some time, it is advisable to switch to soft bristles to avoid further oral problems.

  • Hard bristled toothbrush

Although many people believe that hard bristled toothbrushes are more effective than others, this is not quite the case. Indeed, the opposite is true. Hard bristles cannot easily reach the spaces between the teeth and make enamel and gums more fragile.

Toothbrush designs based on shape of the toothbrush head

Toothbrush head shapes are of two types, and each has its specific dental use.

  • Conventional shape

Conventional-shaped brushes are the first type to be introduced. They offer a larger surface area. They are most common and cannot often reach molars and other corners of the mouth. This can result in cavities or other issues. The toothbrush head is effective in cleaning the tooth surface. Conventional toothbrushes have heads that are rectangular in shape. With this design, they can effectively clean the surface of every tooth.

  • Diamond shape

Diamond shape toothbrushes have the tips narrower than that of the conventional toothbrush. These are designed so that this modified tip can gain access easily to the posterior teeth. It can reach the furthermost molars, which is an advantage over conventional toothbrushes. When brushing, the bristle shapes wrap around each tooth, giving a more thorough cleaning.

  • Deep-grooved shape

This design enables the user to place the toothbrush bristles at an angle of 45º. They are used as one of the most effective means of controlling plaque.

Toothbrush head shape only should not be considered in selecting one for dental use. The size of the selected toothbrush head must be according to the size of the oral cavity. As a result of different oral cavity sizes, we have toothbrushes of different head sizes.

The size of a toothbrush head ranges from 0.5 inches to 1.5 inches. Every individual can choose a comfortable size and design to suit the mouth.

Toothbrush designs based on bristle pattern

We have different bristle patterns, and each pattern has its specific use.

  • Block pattern

These bristles are arranged neatly like a block. The bristles are the same in length and are the most common bristles types and effectively clean the teeth.

  • V-shape pattern or Wavy pattern

These bristles are arranged to form a wavy pattern or V-shape. This design is made to give the bristles a better contact with the teeth. This includes the areas around the tooth surfaces.

  • Multi-level trim pattern

Bristles of this type are arranged on multi-levels. With this design, the brush can reach areas very difficult to reach. This toothbrush can help clean difficult areas between teeth and difficult areas on the crown. Multi-level bristles used with rubber circles at the centre can be used to remove supra gingival plaque.

  • Criss-cross pattern

This Toothbrush design is used to lift and remove dental plaque.

  • Polishing cup bristles

These bristles patterns are specially designed to clean stains on the surface of the teeth effectively.

Any of these toothbrush head designs can clean the teeth effectively if the correct techniques are used. Some have additional functions like plaque removal.

Toothbrush designs based on handle design

The texture and design of toothbrushes handles are not simply to attract consumers. We have a different variety created to help users hold firmly and brush their teeth effectively.

  • Straight handle

Conventional toothbrushes are usually with straight handles. This makes them easy to control. Toothbrushes with straight handles can remove more plaque than angled toothbrushes. If you want plaque removal, it’s better to go for straight handles.

  • Contra-angle handle

The Contra-angle handle design is similar to that of a dental instrument. This design is made to access areas that are difficult to clean. This handle type makes it easier to reach the inner surfaces of the front teeth. If your purpose is to collect excessive tartar in the inner areas of the teeth, go for an angled toothbrush.

  • Flexible handle

A flexible toothbrush handle reduces gum injury resulting from brushing with excessive force. The handle type is good for people with sensitive gums or gum disease.

  • Slip prevention grip handle

The slip prevention grip handle is designed to ensure the toothbrush does not slip away when brushing our teeth. It is used to maintain hold for people. It is specially designed for the dental care of people with arthritis or other manual dexterity.


Any of these toothbrush designs do not have a complete tooth cleaning effect. You need to make your choices based on your personal dental need. Understanding the features of each toothbrush will help to maintain oral hygiene properly and effectively. To meet your particular dental need, you to consider all these features before making your choice.
