A dental procedure is any treatment performed by a dentist or dental specialist on your teeth, gums, jaw, or surrounding tissues. That covers a wide range, from a routine cleaning that takes 30 minutes to oral surgery that requires general anesthesia. Understanding the main categories helps you know what to expect when your dentist recommends one.
Preventive Care: Cleanings and Exams
The most common dental procedure is a professional cleaning and exam, typically done every six months. During this visit, a dentist or hygienist examines your mouth for signs of cavities, gum disease, and even oral cancer by checking your tongue, jaw, and neck. They use special instruments to measure gum health and may take X-rays to spot problems invisible to the naked eye.
The cleaning itself involves scraping away plaque (the sticky film of bacteria that builds up on teeth), then polishing with a gritty paste and a small electric brush to remove surface stains. This is the foundation of dental care, and for many people, it’s the only procedure they need regularly.
Fillings and Restorations
When a cavity forms, a filling restores the damaged tooth. Your dentist removes the decayed portion and fills the space with one of several materials, depending on the location and size of the cavity.
- Composite resin (tooth-colored fillings) blends acrylic resin and fine glass particles. These are popular for front teeth and visible areas because they match your natural tooth color.
- Amalgam (silver fillings) combines silver, tin, copper, and mercury. These are typically used on back teeth that handle heavy chewing pressure, since amalgam is extremely durable.
- Ceramic fillings are made of porcelain, resist staining, and are often used for larger restorations like inlays and onlays.
- Glass ionomer fillings release fluoride to help prevent further decay but are less durable, so they work best in areas that don’t bear much chewing force.
Crowns and Veneers
When a tooth is too damaged for a simple filling, a crown covers the entire tooth to restore its shape and strength. Crowns are about 2 millimeters thick and can be made of porcelain, metal alloy, or a combination. They’re the go-to option when a tooth has a large filling, a crack, significant decay, or has undergone a root canal. Placing a crown requires filing down the existing tooth to make room.
A veneer, by contrast, is a thin shell (about 1 millimeter) bonded to just the front surface of a tooth. Veneers are primarily cosmetic. They correct discoloration, minor chips, or slight shape irregularities on front teeth. Preparation is less invasive since only about half a millimeter of enamel is removed from the tooth’s surface. If the underlying tooth structure is mostly intact and you’re looking to improve appearance, a veneer is usually the better choice. If the tooth is structurally compromised, a crown is the way to go.
Root Canals
A root canal treats infection deep inside a tooth. The soft tissue inside your tooth, called the pulp, contains nerves and blood vessels. When it becomes infected or inflamed from deep decay, a crack, or trauma, a root canal removes the damaged tissue and saves the tooth.
The procedure typically takes 60 to 90 minutes and sometimes requires more than one visit. After numbing the area, the dentist places a small rubber sheet to keep things dry, drills a small opening in the tooth, removes the infected pulp with tiny instruments, cleans and disinfects the interior, then fills the empty space with a rubber-like material. A temporary filling seals the tooth until a permanent crown is placed at a follow-up visit to protect the tooth long-term.
Root canals are often performed by endodontists, specialists who focus exclusively on the interior structures of teeth. They also handle more complex cases like retreating a root canal that didn’t fully resolve or surgically removing the tip of a tooth root when infection persists.
Tooth Extractions
Extraction means removing a tooth entirely. The most familiar version is wisdom tooth removal. Wisdom teeth often need to come out because they’re impacted (stuck beneath the gum or growing at an angle), which can cause pain, infection, gum disease, decay, or damage to neighboring teeth. Some dentists recommend removing wisdom teeth preventively, even before symptoms appear, because problems tend to develop later.
A simple extraction is performed on a tooth that’s fully visible above the gum line. Surgical extraction is needed when a tooth is impacted or broken below the surface. This involves cutting the gum tissue and sometimes removing a small amount of bone around the tooth. Surgical extractions often use deeper sedation or general anesthesia.
Deep Cleanings for Gum Disease
If gum disease has progressed beyond what a standard cleaning can address, your dentist may recommend scaling and root planing, commonly called a deep cleaning. This procedure targets bacteria and hardened tartar that have built up below the gum line, around the roots of your teeth.
After numbing the gums with local anesthesia, the dentist uses hand tools or ultrasonic instruments to scrape away deposits from both above and below the gum line (scaling), then smooths the tooth roots (planing) so gums can reattach more easily. Antibiotics may be placed around the roots or prescribed afterward to fight remaining bacteria. The goal is to stop gum disease from progressing and prevent tooth loss.
Deep cleanings are frequently performed by periodontists, specialists who focus on the gums and the bone supporting your teeth. Periodontists also place dental implants and perform gum grafts when tissue has receded significantly.
How Pain Is Managed
Most dental procedures use local anesthesia, an injection of numbing medication (like lidocaine) that blocks pain in a specific area while you stay fully awake. This is sufficient for fillings, root canals, deep cleanings, and many extractions.
For more involved procedures or significant anxiety, sedation is available at several levels. Mild sedation keeps you awake but relaxed. Moderate sedation may cause you to doze off, though you’ll wake easily. Deep sedation puts you nearly to sleep but lets you breathe on your own. General anesthesia, used for complex oral surgery, makes you completely unconscious. Sedation is typically delivered through an IV, and the level chosen depends on the procedure and your comfort level.
What Recovery Looks Like
Recovery varies significantly depending on the procedure. A filling or cleaning requires no downtime at all. More involved procedures follow a predictable pattern.
After oral surgery like an extraction, pain typically peaks and then improves by the third day. Swelling is worst at 48 to 72 hours, and bruising, if it occurs, fades over 7 to 14 days. Jaw stiffness is common and follows the same timeline. Most stitches dissolve on their own within a week, though some types last up to two weeks. You’ll want to avoid crunchy or sharp-edged foods for four to five days.
After a root canal or endodontic surgery, swelling and bruising peak at 48 to 96 hours, and minor oozing is normal for the first week. Hot liquids and crunchy foods should be avoided for three days. Over-the-counter ibuprofen is the standard recommendation for managing pain, with acetaminophen as an alternative.
If you received sedation, don’t drive or make important decisions until the following morning, and avoid alcohol for 24 hours. Smoking after any surgical dental procedure triples the risk of dry socket, a painful complication where the blood clot in an extraction site is lost, so it’s worth avoiding for at least 24 hours and ideally longer.
