Where Is the Palatal in the Mouth?

In dentistry, palatal means relating to or facing the palate—the roof of the mouth. When a dentist describes the “palatal surface” of a tooth, they usually mean the inner surface of an upper tooth that faces towards the palate.

For example, the surface behind an upper front tooth is its palatal surface. On the lower teeth, the corresponding inner surface is normally called the lingual surface because it faces the tongue. Understanding terms such as palatal, lingual, buccal and labial can make dental notes and treatment explanations much easier to understand.

What Is the Palate?

The palate forms the roof of the mouth and separates the oral cavity from the nasal cavity. It plays an important role in eating, swallowing and speech.

It has two main parts:

• Hard palate: The firm, bony front portion of the roof of the mouth. It makes up roughly the front two-thirds of the palate and provides a surface against which the tongue can press food during chewing and swallowing.
• Soft palate: The flexible muscular area at the back of the roof of the mouth. It rises during swallowing to help close the passage towards the nose and also contributes to speech.

The small structure hanging from the back of the soft palate is the uvula.

Where Is the Palatal Surface of a Tooth?

Every upper tooth has a surface facing towards the palate. This is called its palatal surface.

For the upper front teeth, this is the surface behind the tooth that your tongue can touch. Upper premolars and molars also have palatal surfaces facing the inside of the upper dental arch.

During a dental examination, your dentist checks all tooth surfaces, including areas that may be difficult to see yourself.

Palatal vs Lingual, Buccal and Labial: What Is the Difference?

Dentists use directional terms to describe exactly where something is located on a tooth:

• Palatal: The inner surface of an upper tooth facing the palate
• Lingual: The inner surface of a lower tooth facing the tongue
• Buccal: The outer surface of a back tooth facing the cheek
• Labial: The outer surface of a front tooth facing the lips
• Mesial: The surface facing towards the centre line of the dental arch
• Distal: The surface facing away from the centre line
• Occlusal: The chewing surface of a premolar or molar

These terms allow dentists to describe the exact location of decay, fillings, cracks and other dental findings.

What Is a Palatal Filling?

A palatal filling simply means a restoration involving the palate-facing surface of an upper tooth.

Decay can occur on palatal surfaces just as it can elsewhere on a tooth, although certain areas are more vulnerable than others depending on tooth shape, plaque accumulation, diet and oral hygiene.

If decay is detected, it may be repaired with a dental filling where appropriate.

What Is a Palatal Cusp?

Upper premolars and molars have raised areas on their chewing surfaces called cusps. The cusps positioned towards the palate are known as palatal cusps.

These cusps are important in the way the upper and lower teeth contact during biting and chewing. Your dentist or orthodontist may therefore refer to palatal cusps when discussing the bite or tooth position.

What Is a Palatal Expander?

A palatal expander, also called a maxillary expander, is an orthodontic appliance used to widen a narrow upper jaw in selected patients.

The appliance is normally connected to the upper teeth and spans across the palate. Gradual pressure is used to increase the width of the upper dental arch or jaw.

Expansion is particularly useful in growing children with certain problems such as a narrow upper jaw or crossbite. Glow Dental provides early orthodontic treatment, including rapid maxillary expansion where clinically appropriate.

Adults can also require expansion in selected cases, although the technique may differ because the upper jaw is no longer growing in the same way. A specialist orthodontic assessment can determine which approach is appropriate.

What Does Palatal Mean in Orthodontics?

In orthodontics, a tooth may be described as being positioned or moved palatally if it lies or moves towards the inside of the upper dental arch.

For example, an upper canine may erupt further towards the palate rather than into its normal position in the dental arch. Orthodontic treatment can sometimes be used to guide an appropriately positioned tooth into alignment.

Glow Dental provides both specialist orthodontic treatment and early orthodontic assessment for children.

What Does the Palate Do?

The palate has several important functions:

• Eating: The tongue presses food against the hard palate while preparing it for swallowing.
• Swallowing: The soft palate elevates to help prevent food and liquid passing upwards into the nasal cavity.
• Speech: The tongue and palate work together to produce many speech sounds, while movement of the soft palate helps control airflow through the mouth and nose.
• Separation of the mouth and nose: The palate forms an anatomical barrier between the oral and nasal cavities.

Common Problems Affecting the Palate

Burns and traumatic ulcers

The hard palate can easily be burned by very hot food or drinks. Sharp or hard foods can also scratch the tissue and produce a temporary sore or ulcer.

Most minor mouth ulcers heal within one or two weeks. An ulcer that remains for more than three weeks, repeatedly bleeds or looks unusual should be checked by a dentist or doctor.

Glow Dental includes oral cancer screening as part of routine dental examinations.

Torus palatinus

A torus palatinus is a hard bony prominence that usually develops along the middle of the hard palate. It is a common and benign anatomical variation rather than a cancerous growth.

Most palatal tori require no treatment. Removal may occasionally be considered if a large torus is repeatedly traumatised or interferes with the fitting of a dental appliance such as an upper denture.

Denture irritation

Many conventional upper dentures cover part of the hard palate. Poorly fitting dentures can sometimes rub the palatal tissue and cause soreness or ulceration.

If a denture repeatedly causes pain or leaves a persistent sore area, it should be checked rather than simply tolerated. Find out more about dentures at Glow Dental.

Cleft palate

A cleft palate is a developmental condition in which the palate does not completely join during pregnancy, leaving an opening in the roof of the mouth.

Children with a cleft palate are cared for by specialist multidisciplinary cleft teams and may need surgery, speech and hearing support, dental care and orthodontic treatment as they grow.

Routine preventive dental care is also particularly important for children, and Glow Dental provides children’s dentistry for young patients.

Why Might the Roof of Your Mouth Hurt?

Pain on the palate has many possible causes and is often minor. Common examples include a burn from hot food, an ulcer, irritation from a denture, trauma from sharp food or an infection.

You should arrange an assessment if the problem is severe, repeatedly returns or does not heal as expected. In particular, a mouth ulcer lasting more than three weeks, an unexplained lump or a persistent red or white patch should be examined.

Can You Get Tooth Decay on the Palatal Side of Teeth?

Yes. Any exposed tooth surface can potentially develop decay if conditions allow plaque bacteria and dietary sugars to repeatedly produce acid against the enamel.

The palatal surfaces of the upper front teeth and back teeth are therefore checked during routine dental examinations, together with the chewing, cheek-facing and between-tooth surfaces.

Frequently Asked Questions About the Word Palatal

What does palatal mean in dentistry?

Palatal means relating to the palate or facing towards it. When used to describe a tooth surface, it normally refers to the inner surface of an upper tooth.

Is palatal the same as lingual?

They describe similar directions but are normally used for different arches. Palatal describes the inner surface of upper teeth facing the palate, while lingual describes the inner surface of lower teeth facing the tongue.

Where is the palatal side of your front teeth?

It is the back surface of your upper front teeth—the surface that faces the roof of your mouth and can be touched by your tongue.

What does palatally positioned mean?

It means something is positioned towards the palate. For example, an upper tooth described as “palatally displaced” sits further towards the inside of the upper dental arch than expected.

Is a lump on the palate normal?

Some people naturally have a harmless bony prominence called torus palatinus. However, not every lump on the palate is a torus. Any new, changing, painful or unexplained lump should be assessed by a dentist or doctor.

Summary: What Does Palatal Mean?

Palatal means relating to or facing the palate, which forms the roof of the mouth. In dental terminology, the palatal surface is the inner surface of an upper tooth, while the corresponding surface of a lower tooth is generally called lingual.

The term appears frequently in dentistry and orthodontics—for example, when describing palatal fillings, palatal cusps, palatally positioned teeth or palatal expanders.

If you have pain, a lump, an ulcer or another concern involving the palate, a dental examination at Glow Dental can help identify the cause. New patients can also find out more about joining Glow Dental.
