A sudden toothache is one of those things that immediately derails your day. Whether it hits you at 3pm on a Tuesday or on a Friday afternoon with the weekend looming, the question is always the same: what do I do right now, and how quickly do I actually need to see a dentist?
The short answer depends on what’s happening. Some dental problems need attention today. Others can wait a day or two without lasting harm. Here’s how to tell the difference — and what to do in the meantime.
What to Do Right Now (First Aid While You Wait)
Before you can get into a dental chair, these steps can help manage pain and reduce the risk of things getting worse.
Rinse with warm salt water. This is genuinely useful, not just an old wives’ tale. Dissolve half a teaspoon of salt in a glass of warm water and swish gently for 30 seconds. It helps flush out debris, reduces inflammation, and can ease mild discomfort.
Apply a cold compress. If your face or jaw is swelling, hold a cold pack — or a bag of frozen peas wrapped in a cloth — against the outside of your cheek for 20 minutes on, 20 minutes off. Cold reduces swelling. Avoid heat, which can make swelling worse.
Take over-the-counter pain relief. Ibuprofen (Nurofen) is generally more effective than paracetamol for dental pain because it reduces inflammation as well as pain. Follow the dosage instructions and only take it if you have no contraindications. Pain relief won’t fix the problem — it just makes the wait more bearable.
Don’t put aspirin directly on the tooth or gum. This is a common home remedy that doesn’t work and can irritate the soft tissue around the tooth.
What Counts as a Dental Emergency
These situations need same-day care — or, if no dentist is available, immediate attention at a hospital emergency department.
A knocked-out tooth. This is the most time-critical dental emergency that exists. If you can find the tooth, hold it by the crown (the white part), not the root. Rinse it gently with milk or saline if it’s dirty — don’t scrub it. Try to place it back in the socket, or keep it in a glass of milk or between your cheek and gum to keep it moist. Get to a dentist within 30 minutes if at all possible. After an hour, the chances of successfully reimplanting the tooth drop significantly.
A cracked or broken tooth with sharp pain. A crack that’s causing severe pain — especially pain that worsens with biting or temperature changes — may mean the nerve is involved. This needs to be assessed without delay.
Severe swelling, especially around the jaw or neck. Swelling that spreads beyond the tooth into your jaw, cheek, or neck can indicate an abscess. Dental abscesses can become serious infections if left untreated. If you have difficulty swallowing or breathing, go to an emergency department immediately — don’t wait to call a dentist.
Uncontrolled bleeding after an extraction or injury. Some bleeding after a tooth removal is normal. Bite down firmly on a gauze pad for 20 to 30 minutes. If bleeding hasn’t slowed after an hour, or is heavy and persistent, call a dentist or present to hospital.
A lost crown with an exposed, painful tooth. If losing a crown has left the underlying tooth sensitive and painful, you’ll want to be seen soon. Temporary dental cement — available from most pharmacies — can protect the tooth in the meantime.
What Can Usually Wait a Day or Two
Not everything that feels urgent is actually urgent. These situations still need attention, but a day or two of careful management won’t cause lasting harm in most cases:
- Mild sensitivity to cold or sweets, without sharp spontaneous pain
- A lost filling that isn’t causing severe pain — dental wax or sugar-free gum can temporarily protect the tooth
- A cracked but not painful tooth
- Minor chips on front teeth with no pain or sensitivity
If you’re unsure, call us. We’d rather help you figure out whether you need to come in than have you wondering about it all evening.
The Problem With Dental Emergencies and Business Hours
Here’s something a lot of people in Adelaide’s northern suburbs know from experience: most dental practices open between 8 and 9am and close at 5pm. If a toothache hits on a Tuesday afternoon while you’re at work at the Technology Park or Edinburgh RAAF, you’re either scrambling to leave early or you’re managing pain through the night hoping to get in the next morning.
It’s worse when you’re coming from a distance. People driving in from Paralowie, Para Hills, or Pooraka on Main North Road aren’t exactly close to the city’s after-hours options. The Mawson Interchange and Salisbury Highway make Mawson Lakes genuinely accessible from most of the northern suburbs — which matters when pain is making you impatient.
At Smile Spot Mawson Lakes, we’re open Monday to Thursday until 7pm, specifically because dental emergencies don’t respect business hours. If something happens on a weekday afternoon, you can often come in directly after work rather than losing pay or annual leave to attend a morning appointment. That’s a genuine difference if you’re one of the 71% of Mawson Lakes residents who commutes by car and keeps a tight schedule.
We do our best to accommodate same-day emergency appointments. Call us as early in the day as you can — (08) 8258 0650 — and we’ll find you a time.
When to Go Straight to Hospital
If you have severe swelling spreading toward your throat or neck, difficulty breathing or swallowing, a high fever alongside tooth pain, or uncontrolled bleeding that isn’t responding to pressure — go directly to an emergency department. These are signs of a potentially serious infection that needs more than dental care alone.
The closest emergency departments to Mawson Lakes are:
- Lyell McEwin Hospital — Haydown Road, Elizabeth Vale (about 10 minutes north on Main North Road) — this is the most convenient ED for most northern suburbs residents
- The Queen Elizabeth Hospital — Woodville Road, Woodville (about 20 minutes south)
- Royal Adelaide Hospital — Port Road, Adelaide (about 25 minutes south via Main North Road)
A hospital ED cannot treat your tooth, but they can manage a spreading infection, control bleeding, and provide stronger pain relief while you arrange dental follow-up. If the situation involves your airway, don’t wait.
