Your smile, in 3D.
An adult mouth has 32 teeth: 8 incisors, 4 canines, 8 premolars and 12 molars (including 4 wisdom teeth). Turn the model below, tap any tooth to learn what it does, or pick a treatment to see exactly where it happens. An illustrative 3D model for patient education — not a diagnostic tool. Your dentist will examine your own teeth and X-rays before recommending treatment.

How to read it
Incisors cut, canines grip, molars grind.
Adults usually have 32 teeth. Dentists number them by quarter: 11–18 upper right, 21–28 upper left, 31–38 lower left and 41–48 lower right. Tap one to learn what it does.

Treatments in 3D
What each view shows you.
Every treatment view highlights the teeth involved and explains, in plain words, what the dentist actually does.
Root canal
Saving a tooth from the inside
The lower left first molar (36) is opened up to show the pulp and its canals running down the roots. In a root canal treatment, the infected pulp is removed and the canals are cleaned, shaped and sealed so the natural tooth can be kept.
Implant
A new root for a missing tooth
Here the lower right first molar (46) is replaced by an implant: a titanium post in the jawbone with a crown fixed on top. The post takes the place of the natural root, so the neighbouring teeth don't need to be trimmed to support it.
Whitening
Lightening the teeth you show
The front teeth that show when you smile, canine to canine in both jaws, are highlighted. Whitening gel lightens stains within the enamel and dentine of natural teeth; it does not change the colour of crowns or fillings.
Braces
Gentle, steady movement
Brackets on each tooth and a connecting wire apply light, steady pressure across the whole arch. Over months, the periodontal ligament and bone around each root remodel, allowing the teeth to move into a straighter position.
Clear aligners
Straightening without wires
A thin, transparent tray fits over all the teeth, and each new set is shaped slightly differently from the last. Worn for most of the day, the series moves teeth in small planned steps, and can be taken out to eat and brush.
Crown & bridge
Filling a gap with a fixed bridge
The upper right second premolar (15) is missing, and a three-unit bridge replaces it using crowns on the neighbouring teeth (14 and 16) as anchors. A single crown works the same way on one tooth, covering and protecting a weak or root-canal-treated tooth.
Gum care
Where tartar likes to build up
The lower front teeth are highlighted with the gums and bone around them, an area where tartar often collects behind the teeth. If plaque stays below the gumline, the gums can become inflamed and the supporting bone can gradually be lost — which is why cleaning and gum care matter.
Wisdom teeth
The last teeth at the back
The lower wisdom teeth (38 and 48) are shown at the very back of the jaw, where there is sometimes not enough room for them to come through straight. A tooth that is stuck or partly through can trap food and cause gum infection; an X-ray shows its position and whether it needs removal.
The 32 teeth
Four kinds of teeth, four jobs.
Teeth are named by type and numbered with the FDI system dentists use: the first digit is the quarter of the mouth (1 upper right, 2 upper left, 3 lower left, 4 lower right), the second counts back from the front tooth.
- Central incisor
- The two front-most teeth in each jaw, with thin, flat edges for biting and cutting into food. Typically one root.
- Lateral incisor
- Sit beside the central incisors and help cut and slice food. Typically one root.
- Canine
- Pointed teeth at the corners of the mouth, used for gripping and tearing food. Typically one long root — the longest in the mouth.
- First premolar
- Have two cusps for tearing and crushing food as it moves towards the back teeth. Upper first premolars often have two roots; lower ones typically have one.
- Second premolar
- Help crush and grind food, bridging the work of the canines and molars. Typically one root.
- First molar
- Large, broad teeth with several cusps that do most of the heavy grinding and chewing. Upper first molars typically have three roots; lower molars typically have two.
- Second molar
- Sit behind the first molars and share the work of grinding and chewing. Typically three roots in the upper jaw and two in the lower, though they are often closer together.
- Third molar
- The last teeth at the back, usually arriving in the late teens or twenties; they grind food when they come in straight. Root shape varies widely and roots are often fused; some people never develop wisdom teeth.
Inside a tooth
What the x-ray view reveals.
Switch on x-ray in the explorer to see through the enamel to the roots and the pulp.
- Enamel
- The hard, outer layer covering the crown of the tooth — the hardest tissue in the body. It protects the tooth from chewing forces and temperature, but once lost it does not grow back.
- Dentine
- The yellowish layer under the enamel that makes up most of the tooth. It contains tiny tubules, which is why exposed dentine can feel sensitive to hot, cold or sweet things.
- Pulp
- The soft centre of the tooth, containing nerves and blood vessels, running from the crown down through the root canals. When decay or a crack reaches the pulp, it can become inflamed or infected — this is what a root canal treatment cleans out.
- Root & cementum
- The root anchors the tooth in the jawbone and sits below the gumline. It is covered by cementum, a thin bone-like layer that the ligament fibres attach to.
- Gums (gingiva)
- The pink soft tissue that wraps around the neck of each tooth and covers the jawbone. Healthy gums are firm and don't bleed when you brush; bleeding is often an early sign of gum inflammation.
- Periodontal ligament
- A thin layer of fibres that holds the root in its socket and acts like a shock absorber when you bite. It's also what allows teeth to move gradually with braces or aligners.
- Alveolar bone
- The part of the jawbone that forms the sockets holding the teeth. Untreated gum disease can wear this bone away, and enough healthy bone is needed to place a dental implant.
