Common Dental Problems
Dental problems are very common, but they are not always obvious straight away. A toothache is a clear sign that something may be wrong, but other symptoms can be easier to miss. Bleeding gums, bad breath, tooth sensitivity, jaw pain, worn teeth or a small chip can all be signs that your mouth needs attention.
The good news is that many common dental conditions are easier to treat when they are found early. A regular dental check-up can help detect issues before they become painful, more complex or more expensive to manage.
At 123 Dental in West Leederville, we help patients with a wide range of dental concerns, from tooth decay and gum disease through to cracked teeth, wisdom tooth pain, jaw discomfort and bite issues. If something does not feel right, it is always better to have it checked.

What Are the Most Common Dental Problems?
The most common dental problems include tooth decay, gum disease, tooth sensitivity, toothache, bad breath, cracked or chipped teeth, wisdom tooth pain, teeth grinding, jaw pain, worn enamel and bite or alignment concerns.
Some problems are mild at first. Others can become more serious if left untreated. For example, a small cavity may only need a filling when found early, but deeper decay may eventually affect the nerve inside the tooth. Bleeding gums may seem minor, but they can be an early sign of gum inflammation.
Only a dentist can confirm what is causing your symptoms. However, understanding the warning signs can help you know when to book an appointment.
1. Tooth Decay and Cavities
Tooth decay is one of the most common dental problems. It happens when plaque builds up on the teeth. The bacteria in plaque use sugar from food and drinks to produce acid, which can gradually damage the tooth surface.
In the early stages, tooth decay may not cause pain. Some people notice a white, brown or dark spot on the tooth. Others may feel sensitivity when eating or drinking something cold, sweet or hot. As decay progresses, it can lead to a cavity, toothache or infection.
Common signs of tooth decay include:
- Sensitivity to cold, sweet or hot foods and drinks
- Toothache or pain when biting
- Visible holes or pits in the teeth
- Brown, black or white staining
- Food getting caught in one area
- Bad breath or a bad taste
Treatment depends on how advanced the decay is. Early enamel changes may be managed with fluoride and better home care. A cavity usually needs a filling. If the decay has reached the nerve, root canal treatment may be needed. In severe cases where the tooth cannot be saved, extraction may be considered.
The best way to reduce your risk is to brush twice daily, clean between your teeth, limit frequent sugary snacks and drinks, and book regular dental check-ups.
2. Gum Disease
Gum disease is another very common dental issue. It occurs when plaque and bacteria irritate the gums and surrounding tissues. In its early stage, gum disease is often called gingivitis. This may cause red, swollen or bleeding gums.
If gum disease progresses, it can affect the structures that support the teeth. This more advanced stage is often called periodontitis. It can lead to gum recession, loose teeth, changes in bite and, in serious cases, tooth loss.
Common signs of gum disease include:
- Bleeding when brushing or flossing
- Red, swollen or tender gums
- Persistent bad breath
- A bad taste in the mouth
- Gums pulling away from the teeth
- Teeth looking longer than they used to
- Loose teeth
- Pain when chewing
Gum disease can start quietly, which is why regular check-ups and professional cleans are important. A scale and clean can remove plaque and hardened tartar that brushing at home cannot remove. More advanced gum disease may need deeper cleaning and ongoing periodontal care.
Bleeding gums should not be ignored. Even if there is no pain, it is worth having your gums checked.
3. Tooth Sensitivity
Tooth sensitivity is a sharp or uncomfortable feeling when your teeth are exposed to cold, hot, sweet or acidic foods and drinks. Some people notice sensitivity when brushing or breathing in cold air.
Common causes of tooth sensitivity include:
- Worn enamel
- Gum recession
- Tooth decay
- Cracked teeth
- Teeth grinding
- Acidic foods and drinks
- Recent dental treatment
- Brushing too hard
A sensitive tooth may be caused by something simple, but it can also be a sign of decay, a crack, gum recession or enamel wear. If sensitivity is new, sharp, localised to one tooth or getting worse, it is best to book a dental check-up.
Treatment depends on the cause. Your dentist may recommend a sensitive toothpaste, fluoride treatment, changes to brushing technique, a filling, treatment for gum recession or care for a cracked tooth.
4. Toothache or Dental Pain
Toothache is one of the main reasons people book a dental appointment. Dental pain can feel dull, sharp, throbbing, constant or triggered by biting. It may come and go, or it may worsen over time.
Common causes of toothache include:
- Tooth decay
- A cracked tooth
- An infected tooth
- Gum disease
- Food trapped between teeth
- Wisdom tooth problems
- Teeth grinding
- Dental trauma
Pain is your body’s way of telling you something needs attention. A toothache that settles temporarily can still come back, especially if the cause has not been treated.
You should book a dental appointment if tooth pain lasts more than a day or two, affects sleep, worsens when biting, or is paired with swelling. If you have facial swelling, fever, difficulty swallowing or difficulty breathing, seek urgent medical help.

5. Cracked, Chipped or Broken Teeth
A cracked, chipped or broken tooth can happen suddenly, or it can develop gradually over time. Some cracks are caused by biting something hard. Others may be linked to teeth grinding, large old fillings, trauma or natural wear.
Common signs of a cracked or chipped tooth include:
- A rough or sharp edge
- Pain when chewing
- Sensitivity to cold or heat
- Pain that comes and goes
- A visible chip or fracture
- Swelling near the tooth
- Food catching around the damaged area
Small chips may be repaired with smoothing or tooth-coloured bonding. Larger breaks may need a dental crown to protect the tooth. If the crack reaches the nerve, root canal treatment may be required before the tooth is restored. If the tooth is too badly damaged, extraction may be needed.
It is best to have a broken tooth checked early. Even a small chip can expose the tooth to further wear, sensitivity or decay.
6. Bad Breath
Bad breath is common from time to time, especially after certain foods or first thing in the morning. However, persistent bad breath can be a sign of an underlying dental problem.
Common dental causes of bad breath include:
- Plaque build-up
- Gum disease
- Tooth decay
- Food trapped between teeth
- Dry mouth
- Poor tongue cleaning
- Infected teeth
- Ill-fitting dental appliances
Bad breath is not something to feel embarrassed about. Dentists see this concern often, and the cause can usually be investigated in a practical way.
Improving brushing, flossing and tongue cleaning may help. If bad breath continues, a dental check-up can identify whether gum disease, decay, dry mouth or another issue is contributing.
7. Teeth Grinding and Jaw Pain
Teeth grinding and clenching are also known as bruxism. Some people grind during the day, while others do it during sleep without realising. Over time, grinding can place pressure on the teeth, jaw joints and facial muscles.
Signs of teeth grinding may include:
- Worn or flattened teeth
- Jaw pain or tightness
- Morning headaches
- Tooth sensitivity
- Cracked or chipped teeth
- Clicking or discomfort in the jaw
- Tired facial muscles
- Disturbed sleep
Stress, sleep habits, bite issues and lifestyle factors can all play a role. Treatment depends on the cause and severity. A dentist may recommend a custom bite splint to help protect the teeth from grinding forces during sleep.
If you regularly wake with jaw tension or headaches, or you have noticed your teeth wearing down, it is worth booking a dental assessment.
8. Wisdom Tooth Problems
Wisdom teeth are the back molars that usually come through in the late teens or early adulthood. Not everyone has problems with them, but wisdom teeth can cause pain when there is not enough room for them to come through properly.
Common signs of wisdom tooth problems include:
- Pain at the back of the mouth
- Swelling around the gum
- Food trapping behind the molars
- Difficulty opening the mouth fully
- Bad taste or bad breath
- Tenderness when chewing
- Recurring gum infection around the tooth
A dentist may take an X-ray to check the position of the wisdom teeth and see whether they are impacted, partially erupted or affecting nearby teeth.
Not all wisdom teeth need to be removed. However, removal may be recommended if they are causing repeated pain, infection, decay, gum problems or pressure on nearby teeth.
9. Mouth Ulcers and Oral Sores
Mouth ulcers are common and often heal on their own. They may be caused by accidentally biting the cheek, irritation from a sharp tooth, stress, certain foods or minor trauma.
Common signs include:
- A painful spot inside the mouth
- A round or oval sore
- Stinging when eating spicy, salty or acidic foods
- Irritation from brushing or chewing
Most minor mouth ulcers improve within one to two weeks. However, any ulcer, sore, lump or patch that does not heal within two weeks should be checked by a dentist or doctor. This is especially important if it is painless, growing, bleeding or keeps returning in the same place.
A dentist can check whether the sore is linked to trauma, infection, a sharp tooth, a dental appliance or another oral health concern.
10. Crowded, Gapped or Misaligned Teeth
Bite and alignment problems are not always just cosmetic. Crowded, gapped or misaligned teeth can affect how the teeth meet, how easy they are to clean and how confident you feel when smiling.
Common alignment concerns include:
- Crowded teeth
- Gaps between teeth
- Deep bite
- Underbite
- Crossbite
- Open bite
- Teeth that have shifted over time
Crowded teeth can make brushing and flossing more difficult, which may increase the risk of plaque build-up. Bite issues can also place uneven pressure on certain teeth.
Treatment depends on your goals, age, oral health and the type of alignment concern. Options may include Invisalign, other orthodontic care or cosmetic dental treatments for selected cases.
If you are unsure whether your bite or alignment is affecting your oral health, a dental consultation can help you understand your options.
When Should You See a Dentist?
You should see a dentist if you notice any ongoing change in your teeth, gums, mouth or jaw. Pain is not the only reason to book an appointment.
Book a dental check-up if you have:
- Toothache lasting more than a day or two
- Bleeding gums
- Swollen, red or tender gums
- Persistent bad breath
- A cracked, chipped or loose tooth
- Pain when biting or chewing
- Sensitivity that is getting worse
- Jaw pain, clicking or morning headaches
- Wisdom tooth pain
- A mouth ulcer or sore that does not heal within two weeks
- A change in the way your teeth fit together
Dental problems are usually easier to manage when treated early. Waiting until pain becomes severe can sometimes mean the problem needs more complex treatment.
How Dentists Treat Common Dental Problems
Treatment always depends on the cause of the problem. At your appointment, your dentist may examine your teeth and gums, ask about your symptoms, check your bite and take X-rays if needed.
Common treatments for dental problems may include:
- Professional scale and clean
- Fluoride treatment
- Tooth-coloured fillings
- Dental crowns
- Same day crowns
- Root canal treatment
- Wisdom tooth removal
- Bite splints for grinding
- Gum disease treatment
- Invisalign or other alignment options
- Emergency dental treatment
- Tooth extraction when a tooth cannot be saved
A good dental appointment should help you understand what is happening, what your options are and what treatment is recommended. You should feel comfortable asking questions before making a decision.
How to Prevent Common Dental Problems
Not every dental problem can be prevented, but good daily care can lower your risk of decay, gum disease, enamel wear and other common issues.
Helpful habits include:
- Brush twice daily with fluoride toothpaste
- Clean between your teeth with floss or interdental brushes
- Limit frequent sugary snacks and drinks
- Drink plenty of water
- Clean your tongue if you notice coating or bad breath
- Avoid using your teeth to open packaging
- Wear a mouthguard when playing contact sport
- Ask about a bite splint if you grind your teeth
- Book regular dental check-ups and cleans
- Do not ignore early warning signs
Small habits make a big difference over time. For example, bleeding when brushing might seem minor, but it can be an early sign that plaque is irritating the gums. Treating this early may help prevent more serious gum problems.

FAQs About Common Dental Problems
What is the most common dental problem?
Tooth decay and gum disease are among the most common dental problems. Tooth decay can lead to cavities, while gum disease can cause bleeding, inflammation, gum recession and long-term damage to the tissues that support the teeth. Both are usually easier to manage when detected early.
How do I know if a dental problem is serious?
A dental problem may be serious if you have severe pain, swelling, bleeding gums, pus, a loose tooth, pain when biting, facial swelling or a mouth sore that does not heal. These symptoms should be checked by a dentist as soon as possible.
Can dental problems go away on their own?
Some minor irritation may settle, but many dental problems do not go away on their own. Tooth decay, gum disease, cracked teeth and dental infections usually need professional care. Pain that disappears temporarily does not always mean the problem has healed.
Why do my teeth hurt when I eat or drink something cold?
Cold sensitivity can be caused by worn enamel, gum recession, tooth decay, a cracked tooth or recent dental work. If the sensitivity is sharp, new, localised to one tooth or getting worse, it is best to book a dental check-up.
Why do my gums bleed when I brush?
Bleeding gums are often a sign of gum inflammation caused by plaque build-up. It may also happen if you have changed your flossing routine, but regular bleeding should not be ignored. A dentist can check your gum health and recommend the right treatment.
Is bad breath a dental problem?
Bad breath can be linked to dental problems such as plaque build-up, gum disease, tooth decay, dry mouth or trapped food. If bad breath does not improve with brushing, flossing and tongue cleaning, it is worth having your teeth and gums checked.
When is a toothache an emergency?
A toothache may need urgent attention if the pain is severe, keeps you awake, is paired with swelling, or makes it hard to bite, chew or open your mouth. If you have facial swelling, fever, difficulty swallowing or difficulty breathing, seek urgent medical help.

How often should I see a dentist?
Many patients benefit from a dental check-up every six months, but the right timing depends on your teeth, gums, risk of decay and any existing dental concerns. Your dentist can recommend a check-up schedule based on your individual oral health.
