A toothache can make everyday activities such as eating, drinking, sleeping, or concentrating uncomfortable. Sometimes tooth pain is temporary, while persistent or recurring discomfort may indicate an underlying dental concern that needs professional attention.

Tooth pain can have several possible causes, including tooth decay, sensitivity, a cracked tooth, gum problems, or inflammation around a tooth. Because the cause is not always obvious from the symptoms alone, a dental examination can help determine what may be contributing to the discomfort.

If you are looking for a family dentist in Bells Corners, Nepean, Kanata, Stittsville, or the surrounding Ottawa area, Robertson Family Dentistry provides dental care for patients experiencing a range of routine and urgent dental concerns.

What Is a Toothache?

A toothache is pain or discomfort affecting a tooth or the area around it. The sensation can range from mild sensitivity to more noticeable or persistent pain.

The way a tooth hurts can sometimes provide clues about what is happening.

You may experience:

• Sharp pain when biting
• Sensitivity to hot or cold foods
• A dull or constant ache
• Throbbing discomfort
• Pain around the gumline
• Discomfort that comes and goes
• Pain that becomes more noticeable at night

However, symptoms alone cannot always identify the cause. A dentist may need to examine the tooth, gums, bite, and surrounding structures to determine what should be investigated further.

What Are the Common Causes of Tooth Pain?

Tooth pain can develop for many different reasons. Some causes involve the tooth itself, while others may involve the gums, jaw, or surrounding tissues.

Tooth Decay and Cavities

One of the common reasons for tooth pain is tooth decay.

When decay progresses, it can affect deeper parts of the tooth. You may notice sensitivity when eating or drinking something hot, cold, or sweet.

Possible signs include:

• Sensitivity to cold drinks
• Discomfort when eating sweets
• Pain while chewing
• A visible dark spot or change in the tooth
• Persistent discomfort

Regular dental examinations can help your dental team monitor your teeth and identify areas that may require attention.

Tooth Sensitivity

Not every sensitive tooth has a cavity.

Tooth sensitivity may occur when the protective enamel becomes worn or when part of the tooth root becomes exposed.

You may notice a short, sharp sensation when consuming:

• Ice cream
• Cold water
• Hot coffee
• Tea
• Sweet foods
• Acidic foods

If sensitivity is frequent, becomes stronger, or affects your normal eating and drinking habits. These are common signs you may need a dental checkup and should consider discussing with a dental professional.

Cracked or Broken Teeth

A cracked or broken tooth can cause pain, particularly when chewing.

Some cracks are difficult to see without a dental examination. You may experience discomfort when biting down or when releasing your bite.

Other possible signs include:

• Sensitivity to temperature
• Pain while chewing
• A rough edge on the tooth
• Intermittent discomfort

The appropriate approach depends on the location and extent of the damage.

Gum Problems

Tooth discomfort can sometimes be associated with gum problems rather than the tooth itself.

Signs that your gums may need attention include:

• Bleeding during brushing or flossing
• Swollen gums
• Redness
• Gum tenderness
• Persistent bad breath
• Gum recession

Gum disease can sometimes develop without significant pain, which is one reason regular dental examinations are important.

Dental Abscess or Infection

A dental abscess is a collection of pus associated with a bacterial infection. It can occur around the tooth or in the surrounding gum tissues.

Possible signs can include:

• Significant tooth pain
• Swelling around the tooth or face
• Sensitivity
• Fever
• A bad taste in the mouth
• Swollen lymph nodes

A dental professional should assess a suspected dental infection. If swelling affects your ability to breathe or swallow, seek urgent medical attention.

Teeth Grinding and Jaw Clenching

Some people regularly clench or grind their teeth, particularly while sleeping.

Over time, this can contribute to tooth wear or jaw discomfort.

You may notice:

• Jaw soreness when waking
• Headaches
• Tooth sensitivity
• Worn tooth surfaces
• Tenderness around the jaw

If you suspect that you grind or clench your teeth, mention it during your dental examination.

Why Does My Tooth Hurt When I Bite Down?

Pain when biting or chewing can have several possible causes.

For example, discomfort when pressure is placed on a particular tooth may be associated with:

• Tooth decay
• A cracked tooth
• An existing restoration
• Inflammation around the tooth
• Changes affecting the supporting tissues
• Bite-related concerns

It can be difficult to determine the cause without an examination.

If one particular tooth consistently hurts when you bite down, it is worth discussing the symptom with your dentist.

Why Does My Tooth Hurt When I Drink Something Cold?

Cold sensitivity is relatively common, but the reason behind it can vary.

Possible contributing factors include:

• Tooth enamel wear
• Exposed tooth roots
• Gum recession
• Tooth decay
• Cracked teeth
• Certain dental procedures

If the sensation is brief and occasional, it may not indicate the same concern as pain that continues after the cold stimulus is removed.

A dental examination can help determine whether further evaluation is appropriate.

Why Is My Toothache Worse at Night?

Some people notice tooth pain more strongly when trying to sleep.

At night, there are fewer daily distractions, which can make discomfort feel more noticeable. Depending on the underlying cause, changes in position or pressure may also affect how symptoms are experienced.

If tooth pain repeatedly wakes you up or interferes with sleep, it is worth arranging a dental evaluation.

You should not rely on pain medication or home remedies as a substitute for identifying the underlying dental concern.

What Can I Do Until I See a Dentist?

If you have tooth pain and are waiting for a dental appointment, there are some general steps you can take to protect the area and maintain oral hygiene.

Consider:

• Gently brushing your teeth
• Cleaning between your teeth carefully
• Drinking water
• Choosing foods that are easier to chew
• Avoiding foods that trigger significant sensitivity
• Keeping the affected area clean

Avoid placing substances directly on the tooth or gums unless specifically recommended by a dental professional.

If you are considering an over-the-counter pain reliever, follow the product directions and speak with a pharmacist or healthcare professional if you are unsure whether it is appropriate for you.

When Is a Toothache a Dental Emergency?

Not every toothache requires emergency dental care, but some symptoms should be assessed promptly.

Contact a dental professional when you experience:

• Severe or persistent tooth pain
• Facial or gum swelling
• A suspected dental abscess
• A broken or knocked-out tooth
• Significant bleeding
• Pain following dental trauma
• A tooth that becomes noticeably loose
• Difficulty opening your mouth

Robertson Family Dentistry provides emergency dental services for dental concerns that require prompt attention.

What Happens During a Dental Examination for Tooth Pain?

If you visit a dentist because of a toothache, the appointment may begin with questions about your symptoms.

Your dental team may want to know:

• When the pain started
• Whether the pain is constant or intermittent
• What triggers the pain
• Whether you have sensitivity to hot or cold
• Whether chewing causes discomfort
• Whether you have noticed swelling
• Whether you recently injured the tooth

The dentist may then examine your teeth and gums and may recommend dental imaging when appropriate.

The type of examination depends on your symptoms and individual circumstances.

When Might a Root Canal Be Considered?

If the inner portion of a tooth becomes inflamed or infected, root canal treatment may be one of the treatment options considered by a dentist.

Symptoms associated with a tooth that may require further evaluation can include:

• Persistent tooth pain
• Sensitivity that lingers
• Pain when chewing
• Swelling around the tooth
• A change in tooth colour

However, these symptoms can have multiple causes. A dental examination is necessary to determine what is happening and whether root canal treatment is appropriate.

How Can Toothaches Be Prevented?

Not every toothache can be prevented, but consistent oral hygiene and regular dental care can support ongoing oral health.

Brush Your Teeth Regularly

Brush your teeth twice a day using fluoride toothpaste.

Pay attention to:

• Front and back surfaces
• Chewing surfaces
• The gumline
• Hard-to-reach areas

Use a gentle brushing technique rather than applying excessive pressure.

Clean Between Your Teeth

Brushing does not clean every surface between teeth.

Depending on your needs, you can use:

• Dental floss
• Interdental brushes
• Other cleaning tools recommended by your dental team

Cleaning between teeth can help remove food particles and plaque from areas that a toothbrush may not reach.

Be Mindful of Sugary Foods and Drinks

Frequent consumption of sugary foods and drinks can contribute to tooth decay. Consider limiting frequent snacking and choosing water between meals. There is a list of foods and drinks that can harm your teeth.

Don’t Ignore Changes in Your Teeth

Small changes can sometimes be easy to overlook.

Pay attention to:

• New sensitivity
• Bleeding gums
• Changes in tooth colour
• Rough or broken areas
• Persistent bad breath
• Pain when chewing

Mentioning these changes during a dental appointment can help your dental team decide whether further evaluation is needed.

Toothache in Bells Corners: When Should You Contact a Dentist?

If you live in Bells Corners or the surrounding Ottawa area, you do not necessarily have to wait until dental pain becomes severe before seeking advice.

Consider contacting Robertson Family Dentistry if you have:

• Persistent tooth pain
• A broken or damaged tooth
• Gum swelling
• Tooth sensitivity that continues
• Pain while chewing
• Symptoms following dental trauma
• Concerns about a possible dental infection

Robertson Family Dentistry provides general and family dental services as well as emergency dental care for patients in Bells Corners and surrounding Ottawa communities.

Toothache and Children

Tooth pain is not limited to adults. Children can also experience discomfort associated with cavities, tooth sensitivity, dental injuries, or developing teeth.

Parents may notice changes such as:

• Avoiding certain foods
• Chewing on one side
• Touching the mouth frequently
• Complaining about tooth pain
• Difficulty sleeping
• Changes in brushing habits

Children may not always be able to explain exactly where the discomfort is coming from.

If your child experiences ongoing dental pain, consider arranging an examination.

Why You Shouldn’t Ignore Persistent Tooth Pain

A toothache is a symptom rather than a diagnosis.

The same type of pain can have different causes, which means treating the symptom alone may not address the underlying concern.

Persistent or recurring discomfort deserves attention, particularly when it is accompanied by swelling, sensitivity, changes in the tooth, or difficulty chewing.

A dental examination can help your dentist determine what needs to be investigated and discuss appropriate next steps.

Frequently Asked Questions About Toothaches

What is the most common cause of a toothache?

Tooth decay is one possible cause of tooth pain, but toothaches can also result from sensitivity, cracked teeth, gum problems, infection, dental trauma, or other conditions. A dental examination is needed to determine the cause.

How do I know if my toothache is serious?

Persistent or severe pain, swelling, fever, a suspected abscess, significant dental trauma, or difficulty swallowing or breathing should not be ignored. Contact a dental professional for guidance.

Can a toothache go away on its own?

Some dental pain may temporarily improve, but the disappearance of pain does not necessarily mean that the underlying cause has resolved. Recurring or persistent symptoms should be evaluated.

Why does my tooth hurt when I bite down?

Pain when biting can have several possible causes, including decay, a cracked tooth, inflammation, or problems involving the supporting structures. A dental examination can help determine the cause.

Why does my tooth hurt when I drink cold water?

Cold sensitivity can be associated with enamel wear, gum recession, exposed roots, decay, cracked teeth, or other dental concerns. If sensitivity is frequent or lingering, consider discussing it with a dentist.

Can gum disease cause tooth pain?

Gum disease can cause gum tenderness, bleeding, swelling, recession, and other symptoms. More advanced periodontal disease can affect the tissues supporting the teeth and may be associated with tooth mobility.

When should I see an emergency dentist for tooth pain?

Prompt dental attention may be appropriate for severe pain, facial or gum swelling, suspected infection, significant dental trauma, a broken or knocked-out tooth, or other urgent symptoms.

What should I do if my tooth breaks?

Keep the area clean, avoid chewing on the affected side, and contact a dental professional for advice. If a piece of the tooth has broken off, keep it and bring it to the appointment if possible.

Can a cavity cause a toothache?

Yes. Tooth decay can cause sensitivity or pain, particularly as it progresses. However, tooth pain does not always mean you have a cavity, so an examination may be needed.

Key Takeaways

• A toothache can have many possible causes, including decay, sensitivity, cracks, gum problems, and infection.
• Persistent or recurring tooth pain should be evaluated rather than ignored.
• Pain when biting or sensitivity to hot and cold can provide useful information but cannot confirm a diagnosis by itself.
