It is easy to put off a dental visit when nothing hurts or to hope a symptom will settle. Some do, but persistent or worsening signs deserve assessment. Earlier diagnosis may preserve more options; it does not guarantee simpler, less uncomfortable, or less costly treatment in every case.
Here are eight warning signs that typically warrant a professional assessment, along with guidance on how often you should be seeing a dentist even when everything feels fine.
1. Persistent Tooth Pain
An occasional twinge that comes and goes is not unusual. But tooth pain that lasts more than a day or two, keeps coming back, or is getting worse is worth investigating. Persistent pain can indicate:
- Decay that has reached the inner layers of the tooth
- A cracked tooth that is not visible to the naked eye
- Infection or abscess forming at the root
- A failing restoration -- an old filling or crown that is breaking down
Over-the-counter pain relief may manage the symptoms temporarily, but it does not treat the underlying cause. If decay or infection is involved, the problem will continue to progress until it is addressed.
Clinical tip: Pain that wakes you up at night, or pain that throbs and intensifies when you lie down, may suggest the nerve inside the tooth is affected. This typically warrants a prompt appointment rather than a wait-and-see approach.
2. Bleeding Gums
Gums that bleed when you brush or floss -- especially if this happens regularly -- are often an early sign of gum disease (gingivitis). Healthy gums should not bleed during normal brushing.
Gingivitis is typically reversible with improved oral hygiene and a professional clean. But if left untreated, it can progress to periodontitis, a more advanced form of gum disease that affects the bone supporting your teeth and may eventually lead to tooth loss.
Other possible causes include aggressive brushing, certain medications (particularly blood thinners), hormonal changes during pregnancy, and vitamin deficiencies. If your gums are bleeding regularly, a dental assessment can help identify the cause and the appropriate response.
3. Increased Sensitivity
A sharp jolt of pain when you eat or drink something hot, cold, sweet, or acidic suggests that the protective layers of your tooth may be compromised. Common causes include worn enamel from grinding or acidic diets, receding gums exposing the root surface, early decay, or a cracked tooth.
Sensitivity can sometimes be managed with desensitising toothpaste, but it is worth having it assessed -- particularly if it is new, worsening, or localised to one tooth.
4. A Loose or Shifting Tooth
Adult permanent teeth should not feel loose. If a tooth moves when you press on it with your tongue or finger, this may indicate advanced gum disease, trauma, chronic grinding that has loosened the attachment, or an abscess affecting the bone around the root.
A loose tooth needs professional assessment. Treatment may involve gum therapy, a splint, a nightguard, or in some cases, extraction and replacement.
5. Jaw Clicking, Popping, or Pain
Clicking or popping sounds when you open and close your mouth, combined with pain in the jaw joint, difficulty opening wide, or headaches, may suggest a temporomandibular joint (TMJ) disorder. Common causes include teeth grinding, bite misalignment, stress-related jaw tension, and arthritis.
Not every click or pop requires treatment -- some jaw sounds are benign and long-standing. But if the clicking is accompanied by pain, locking, or reduced range of motion, a dental assessment can help determine whether intervention is needed.
6. Persistent Bad Breath
Everyone has bad breath from time to time. But bad breath that persists despite regular brushing, flossing, and tongue cleaning can be a sign of gum disease, untreated decay, a failing restoration with gaps that trap bacteria, or dry mouth caused by certain medications.
Persistent bad breath that does not respond to improved oral hygiene is worth investigating. Your dentist can identify the dental causes, and if no dental cause is found, may suggest further investigation with your GP.
7. Swelling in the Gums, Face, or Jaw
Swelling is your body's signal that something is wrong. In a dental context, swelling may indicate an abscess, advanced gum disease with active infection, or an impacted wisdom tooth. A small, localised gum swelling may come and go, creating a false sense that the problem is resolving -- but the underlying infection often persists.
Facial swelling that is spreading, worsening, or affecting your ability to swallow or breathe is a medical emergency. See our guide on dental emergencies for what to do.
8. Tooth Discolouration
A single tooth that has changed colour -- becoming darker, greyer, or yellowish compared to the surrounding teeth -- may indicate nerve death from past trauma, internal decay, or discolouration from older filling materials.
General yellowing across all teeth is usually related to surface staining or natural ageing. But a single discoloured tooth is more likely to have a clinical cause and should be assessed.
Why Waiting Usually Makes It Worse
Many dental conditions are progressive. A small cavity that could be treated with a simple filling may, over months of inaction, progress to the point where it requires a crown, root canal treatment, or extraction. This is not a scare tactic -- it is how decay and infection work when left untreated.
The practical implications of waiting often include:
- More complex treatment -- what starts as a straightforward procedure may require multiple appointments and specialist involvement (see crown vs filling for an example of this progression)
- Higher cost -- a filling from $200 is significantly less than root canal treatment from $1,000 followed by a crown from $1,600. Indicative pricing. Your quote may differ based on clinical assessment.
- More discomfort -- early-stage decay is often painless, while advanced decay and infection typically involve significant pain
- Greater risk of tooth loss -- the further a problem progresses, the less likely the tooth can be saved
In short, the earlier a problem is identified and treated, the simpler and more affordable the solution tends to be.
How Often Should You See a Dentist?
The general recommendation for most adults is a dental check-up and clean every six months. However, the appropriate frequency for you may vary depending on your individual risk factors.
You may benefit from more frequent visits if you have a history of gum disease, are prone to cavities, smoke, have diabetes, are pregnant, or wear braces or aligners. A typical check-up includes a visual examination, X-rays as needed, professional cleaning to remove plaque and calculus, and a discussion of any findings.
At Ivy Dental, a check-up and clean starts from $220. Your dentist will discuss any findings with you and, if treatment is recommended, explain the options, expected costs, and timeframe before proceeding.
Do Not Wait for Pain
One of the most common things dentists hear is, "I should have come in sooner." Many dental conditions do not cause pain until they are well advanced. Regular check-ups are designed to catch problems early -- before they cause symptoms, before they require complex treatment, and before they cost more to fix.
If you are experiencing any of the warning signs listed above, or if it has been more than six months since your last dental visit, book a check-up.
