Did you know that cavities can form anywhere on a tooth? Cavity-causing bacteria can attack all areas of a tooth, including the top, the sides and the root, if it's exposed. A smooth surface cavity may appear on the side or the circumference of a tooth. The good news is, a dental professional can treat this type of cavity and prevent it from growing larger and weakening the tooth structure.
Types of Dental Cavities
Dental professionals categorize cavities according to where they appear on the tooth and their level of decay. As an article in The Journal of the American Dental Association outlines, there are different sites on a tooth where cavities can develop:
- Pits and fissures, or the biting surfaces of your teeth
- Approximal surfaces, where a tooth touches the neighbouring tooth
- Cervical surfaces, which are the parts of the teeth next to the gums
- Smooth surfaces, can occur on the circumference of the tooth or in between the teeth
- Roots, the parts of the tooth below the gumline
When the smooth surface or any other part of the tooth is entirely healthy, it's called a sound surface. The beginning stage of decay is called an initial caries lesion. This early decay often appears as a white spot on the tooth's enamel. At this stage, the surface remains whole and no cavity has formed. The next stage of decay is called a moderate caries lesion; tiny holes may have appeared in the affected area, the beige dentin beneath the enamel may show through or a shallow cavity may have formed. Finally, the most advanced and severe decay is known as an advanced caries lesion. In this final stage, the dentin layer of the tooth is exposed and a full cavity has formed.
Smooth Surface Cavity Treatment
In its earliest stage, decay on the smooth surface of a tooth can be reversed. A study in the Journal of Oral Hygiene & Health mentions that fluoride can help to remineralise areas of early decay in smooth surfaces. Another option is treatment with specialised resin that blocks tiny holes in smooth surface enamel, preventing the growth of bacteria and halting the progress of decay.
If the decay has progressed and a cavity has already developed, your dentist can still provide treatment to prevent the condition from worsening. The National Health Portal of India explains that the treatment for cavities depends on the intensity of tooth decay.
- Early stages of tooth decay can be managed by fluoride treatment. Fluoride toothpaste strengthen the teeth and offer the best protection from tooth decay.
- If you have a cavity in your tooth, your dentist will clean the decayed tooth and then fill the tooth with a filling material. If the damage/ infection of tooth has spread to the pulp (inside the tooth), then a root canal is required.
- In severe cases, when the damage to the tooth cannot be fixed, dentist may pull (extract) the tooth. Replacement of missing tooth is suggested after wound healing.
How to Prevent a Smooth Surface Cavity
Poor oral hygiene is responsible for tooth decay, including smooth surface cavities. The National Health Portal of India further explains that good oral hygiene is the first step to prevent tooth decay, and brush with fluoride toothpaste twice daily. You should also visit your dentist every six months or as often as they recommend. At these appointments, they can check for and treat early decay before it develops into a cavity. If your dentist believes your teeth are at risk of decay, they may advise you to rinse once per day with a fluoride mouthwash. They may also provide in-office fluoride treatments to strengthen your tooth enamel. To further protect your teeth, you might consider drinking your local tap water if it's fluoridated, avoiding snacking or sipping beverages other than water during the day and eating tooth-friendly foods, such as fruits and vegetables.
A smooth surface cavity requires treatment, but it's entirely preventable. Practice good oral hygiene and visit your dentist regularly, so they can spot the early signs of decay that can be reversed.
