Cavities, also known as dental caries or tooth decay, are one of the most common dental problems people face. These tiny holes in the teeth can cause pain and lead to bigger problems if not treated properly. When cavities form, it’s important to visit a dentist to prevent further damage. This article will explain what doctors do for cavities, what happens during treatment, and how you can prevent cavities in the future.
Understanding Cavities
Before looking at how dentists treat cavities, it is important to understand what they are and how they form.
Cavities are the result of tooth decay, which happens when bacteria in the mouth feed on sugars from food and drinks. These bacteria produce acids that slowly wear away the hard outer layer of the tooth, known as enamel. As the enamel weakens, it forms small holes or cavities.
Causes of Cavities
There are several factors that contribute to the development of cavities:
Poor oral hygiene: Not brushing your teeth properly or often enough can leave food particles and plaque behind. Plaque is a sticky film of bacteria that can eat away at tooth enamel.
Eating sugary foods and drinks: Foods like candy, soda, and even some fruit juices can provide the sugars that bacteria thrive on.
Dry mouth: Saliva helps wash away food particles and bacteria. If you have a dry mouth due to certain medications or conditions, you may be more prone to cavities.
Not visiting the dentist regularly: Regular checkups help catch cavities early before they become serious.
How Dentists Diagnose Cavities
To treat cavities, a dentist first needs to diagnose them. This typically happens during a routine dental exam. Here’s how the process works:
Visual Inspection
During your checkup, the dentist will examine your teeth closely. They will look for signs of cavities, such as dark spots or holes in the teeth. The dentist may also use a tool called an explorer, which is a tiny hook, to feel for soft areas on your teeth. If the tooth feels soft, it may indicate a cavity.
X-rays
If the dentist suspects a cavity but cannot see it clearly, they may take X-rays of your teeth. X-rays allow the dentist to see between your teeth and under the surface of your enamel, where cavities can develop.
What Do Doctors Do for Cavities?
Once a cavity is diagnosed, the dentist will discuss the best treatment options. The treatment depends on how severe the cavity is and how much damage has been done to the tooth.
Early Treatment: Fluoride Treatments
In the early stages of tooth decay, the damage may not be severe enough to require a filling. If the cavity is small, the dentist may recommend a fluoride treatment. Fluoride is a mineral that helps to strengthen tooth enamel and can sometimes reverse the early stages of decay.
Fluoride treatments are quick and painless. The dentist may apply fluoride gel or varnish to the affected tooth. Over time, this helps to remineralize the enamel and may stop the decay from progressing.
Fillings for Cavities
When the cavity has grown large enough that the enamel is permanently damaged, the dentist will need to fill the hole. This is the most common way to treat cavities.
Steps for Getting a Filling:
Anesthesia: To make the procedure comfortable, the dentist will numb the area around the cavity with a local anesthetic. This ensures you won’t feel pain during the procedure.
Removing Decay: Once the area is numb, the dentist will use a drill, laser, or air abrasion to remove the decayed portion of the tooth. This step ensures that all the harmful bacteria and weakened enamel are cleaned out.
Cleaning: After the decay is removed, the dentist will clean the cavity to remove any remaining debris.
Filling the Cavity: The dentist will then fill the cavity with a material to restore the tooth’s structure. There are several types of filling materials, including:
Amalgam (silver) fillings: Made from a mixture of metals, these fillings are strong and durable but are visible due to their color.
Composite (tooth-colored) fillings: These fillings blend in with the natural color of your teeth and are often used for cavities in visible areas.
Gold fillings: Made of gold alloy, these fillings are strong and can last a long time but are more expensive than other options.
Porcelain fillings: These fillings look like natural tooth enamel and are often used for larger cavities. They are durable but may be more expensive than composite fillings.
Shaping and Polishing: Once the filling material is in place, the dentist will shape it to match the natural contours of your tooth. Finally, they will polish the filling to smooth it out and ensure that it blends well with the rest of your teeth.
Crowns for Large Cavities
If a cavity is too large for a simple filling, the dentist may recommend a crown. A crown is a cap that fits over the entire tooth to restore its shape and function. Crowns are often made of porcelain, metal, or a combination of both.
Steps for Getting a Crown:
Preparation: The dentist will numb the tooth and remove any remaining decay. They will then shape the tooth so that the crown will fit properly.
Impression: The dentist will take an impression of the tooth to create a custom crown. This impression is sent to a dental laboratory, where the crown is made to fit your tooth perfectly.
Temporary Crown: While the permanent crown is being made, the dentist will place a temporary crown to protect the tooth.
Fitting the Permanent Crown: Once the permanent crown is ready, the dentist will place it over the tooth and make sure it fits comfortably. The crown will be cemented into place.
Root Canals for Severe Cavities
In some cases, a cavity can reach deep into the tooth, affecting the pulp (the soft tissue inside the tooth). When this happens, the tooth may become infected, and the dentist may need to perform a root canal.
A root canal involves removing the infected pulp and cleaning out the root canals of the tooth. After cleaning the area, the dentist will fill the canals with a special material and seal the tooth. A crown is often placed over the tooth afterward to restore its function.
Steps for a Root Canal:
Anesthesia: The dentist will numb the area around the infected tooth to ensure you are comfortable during the procedure.
Removing the Pulp: The dentist will make a small opening in the top of the tooth to access the pulp. The infected tissue will be removed.
Cleaning the Tooth: After removing the pulp, the dentist will clean the root canals to remove bacteria and debris.
Sealing: The cleaned canals will be filled with a special material to seal the tooth and prevent further infection.
Placing a Crown: Finally, a crown will be placed over the tooth to protect it and restore its appearance.
Preventing Cavities
While visiting the dentist is important for treating cavities, prevention is key. Here are some steps you can take to protect your teeth from decay:
1. Brush Your Teeth Regularly
Brush your teeth at least twice a day with fluoride toothpaste. This helps remove plaque and food particles that can lead to cavities. Be sure to brush all surfaces of your teeth, including the back and along the gumline.
2. Floss Daily
Flossing helps remove food particles and plaque from between your teeth, where your toothbrush can’t reach. This is especially important for preventing cavities in hard-to-reach areas.
3. Eat a Healthy Diet
A balanced diet that is low in sugar and high in nutrients will help keep your teeth healthy. Limit sugary snacks and drinks, and try to eat more fruits, vegetables, and whole grains.
4. Drink Water
Drinking water throughout the day helps wash away food particles and bacteria. It also keeps your mouth hydrated, which is important for preventing cavities.
5. Visit the Dentist Regularly
Regular dental checkups are crucial for catching cavities early and preventing serious dental problems. Your dentist can provide fluoride treatments and sealants, which can further protect your teeth from decay.
Conclusion
Cavities are a common dental issue, but with early detection and proper treatment, they can be effectively managed. Dentists use various methods, including fluoride treatments, fillings, crowns, and root canals, to treat cavities and restore tooth health. By maintaining good oral hygiene and visiting the dentist regularly, you can reduce your risk of developing cavities and keep your teeth healthy for years to come.
