What it is

Routine examination of teeth, gums and soft tissues by a dentist. It sits within Oral Health. The table below gives the figures guidance actually works from.

The numbers, in one place

What helps

These are the changes with the clearest evidence behind them. Start wherever it is easiest to start.

• Go at the interval your dentist recommends for you
• Check what dental coverage your plan includes before you need it
• Find out where to get urgent dental care before you need it
• Mention any mouth sore or patch lasting more than two weeks

What to avoid

A few of these are widely believed. That is precisely why they are here.

• Only going when something hurts
• Assuming the same interval is right for everyone
• Ignoring soft-tissue changes because your teeth feel fine

In depth

A dental checkup has two parts that people often blur together: a cleaning, usually done by a dental hygienist, and an examination by the dentist. The cleaning removes tartar that has built up despite brushing and polishes the teeth so plaque has less to cling to. The exam looks for decay, gum disease, cracked teeth, worn fillings, problems with your bite and changes in the soft tissues of the mouth. X-rays are taken when needed to see between teeth and below the gumline.

The interval between visits is not the same for everyone. People with healthy teeth and gums, low decay risk and good home care may need visits less often, while people with gum disease, frequent cavities, dry mouth, diabetes or who smoke may benefit from more frequent visits. Your dentist sets a recall interval based on your history and risk, and it may change over time. The common idea that everyone needs a visit every six months is a convenient default rather than a rule.

One part of the exam that is easy to overlook is the check of the tongue, cheeks, floor of the mouth, palate, lips and throat. Your dentist feels the neck and jaw for lumps and looks for patches, sores or color changes that could be early signs of oral cancer. Many of these changes are painless and hard to see yourself, which is one reason regular visits are worthwhile even if your teeth feel fine.

Signs and symptoms

• Bleeding gums or persistent bad breath
• Tooth sensitivity or pain when chewing
• A broken filling, chipped tooth or rough edge
• A sore, lump or patch in the mouth that lasts more than two weeks
• Clicking or pain in the jaw
• Dentures that no longer fit well

Causes and risk factors

• Your history of decay or gum disease
• Smoking or tobacco use
• Diabetes and other health conditions
• Dry mouth from medicines
• Pregnancy
• Braces, implants, crowns or dentures

How it is checked

A typical visit starts with updating your medical history and medicines, since many health conditions and drugs affect the mouth. The hygienist cleans your teeth, measures gum pockets and may take x-rays. The dentist then examines each tooth, checks fillings and crowns, assesses your bite and jaw, and examines the soft tissues of the mouth and neck. They will discuss any findings and recommend treatment if needed.

X-rays are not routine at every visit. How often they are taken depends on your age, risk of decay and gum disease, and what was found before. Dental x-rays use low doses of radiation, and offices use protective measures. If you are pregnant or think you might be, let the office know. Ask for a written treatment plan with estimated costs if work is recommended.

Treatment and support options

Using dental insurance

Many dental plans cover preventive visits and cleanings at little or no cost, with partial coverage for fillings and lower coverage for major work. Plans often have yearly maximums and waiting periods. Ask your dental office to check your benefits before treatment and request a pre-treatment estimate for larger procedures.

If you have Medicare or Medicaid

Original Medicare generally does not cover routine dental care, but many Medicare Advantage plans include some dental benefits, and separate dental plans are available. Medicaid covers dental care for children, and adult dental benefits vary by state. Contact your plan or state Medicaid office to find out what is covered.

Lower-cost care

Community health centers often provide dental care on a sliding fee scale based on income. Dental schools offer care at reduced cost, provided by students under supervision. Some local health departments and charitable programs also offer dental services. Calling 211 can help you find local options.

Managing dental anxiety

Fear of the dentist is common and can lead people to avoid care until problems are serious. Tell your dental team about your anxiety; they can explain each step, agree on a signal to pause and use numbing or, in some cases, sedation. Starting with a simple visit, such as a cleaning, can help build trust.

Prevention

• Visit at the interval your dentist recommends for you
• Keep an up-to-date list of medicines to share at each visit
• Get recommended treatment early, before problems grow
• Ask about sealants and fluoride for children
• Know how to reach urgent dental care
• Check your mouth yourself between visits

Day to day

Scheduling your next visit before you leave the office makes it easier to stay on track, and reminders can help. Keep a note of your insurance benefits and when they renew, since some plans reset each calendar year. If cost is a concern, ask about phasing treatment over time, starting with the most urgent work. Finding a dentist you trust makes it easier to keep coming back.

Between visits, pay attention to changes such as new sensitivity, bleeding or a sore that does not heal, and call rather than waiting. If you have a dental emergency outside office hours, many practices have an after-hours number. Know where your nearest urgent care or emergency room is for severe swelling or trauma, since spreading dental infections can become dangerous.

For specific groups

Children

The first dental visit is recommended by the first birthday. Regular visits help catch decay early, apply fluoride and sealants, and get children comfortable with the dentist. Dental care for children is a covered benefit under Medicaid and CHIP.

Pregnancy

Dental checkups, cleanings and needed treatment are safe during pregnancy. Hormonal changes can make gums more prone to inflammation, so keeping up visits is helpful. Tell your dentist you are pregnant so they can plan care accordingly.

Older adults

Dry mouth, root decay, gum disease and denture problems become more common with age, and the risk of oral cancer rises. Regular visits remain important even if you have few or no natural teeth, since the soft tissues and denture fit still need checking.

Questions to ask your doctor

• How often should I come in, given my risk?
• Do I need x-rays today, and why?
• Did you check for signs of oral cancer?
• What treatment is most urgent, and what can wait?
• How much will this treatment cost with my insurance?
• Is there anything I should change in my home care?

More questions, answered

Do I need a checkup if nothing hurts?

Yes. Decay and gum disease often cause no pain until they are advanced, and oral cancer is frequently painless early on. Regular checkups find problems when they are smaller, easier and less costly to treat.

Are dental x-rays safe?

Dental x-rays use very low doses of radiation, and dentists take them only when they are needed to diagnose problems. Protective measures are used. Tell your dentist if you are pregnant so they can decide whether x-rays can wait.

Why does my hygienist measure my gums?

Measuring the depth of the space between each tooth and gum shows whether gum disease is present and whether it is getting better or worse. It is one of the main ways to detect periodontitis early.

What should I do in a dental emergency?

Call your dentist, who may have an after-hours line. For a knocked-out adult tooth, keep it in milk and get care immediately. Go to the emergency room or call 911 for swelling that affects breathing, swallowing or the eye.

Can I get a cleaning without an exam?

Most dental offices combine cleanings with an exam so problems are not missed. The exam includes checking for decay, gum disease and oral cancer, which is a big part of the value of the visit.

Is it too late to start going to the dentist?

No. It is never too late. Even if it has been years, a dentist can assess your mouth and help you make a plan, starting with the most urgent needs. Telling them how long it has been helps them prepare.

When to speak to a doctor

See a dentist or your doctor promptly for any mouth sore, red or white patch, lump or persistent hoarseness lasting more than two weeks — these need checking for oral cancer. Seek urgent dental care for facial swelling, fever with toothache, or bleeding after an extraction that will not stop. Call 911 or go to the ER for swelling that affects breathing or swallowing.
