What many people don’t realise is that the foods you choose during a toothache can make a real difference. The wrong choices can trigger sharp pain, inflame already-irritated tissue, and even speed up the damage. According to the Australian Institute of Health and Welfare, around one in five Australian adults experienced toothache in the past 12 months so if you’re dealing with it right now, you’re in very good company.

This blog guide covers which foods to avoid with a toothache, what’s safe to eat while you’re sore, and the warning signs that mean it’s time to stop managing pain at home and see a dentist.

Why Does Food Make a Toothache Worse?
What’s Actually Causing Your Tooth Pain?
Before we get to the food list, it helps to understand what’s happening inside your tooth. A toothache occurs when the nerves inside or around the tooth become irritated or inflamed. Common causes include tooth decay, a cracked tooth, a loose or broken filling, gum disease, or a dental abscess.
The good news? Most of these are very treatable — especially when caught early. If you’re not sure what’s ...
... behind the pain, our toothache relief page walks through the most common causes and what to expect.

How Food Choices Affect Healing
When a tooth is already sensitised or infected, certain foods directly aggravate the nerve. Sugary foods feed bacteria and accelerate decay. Acidic foods erode enamel and sting exposed dentine. Hard foods add pressure to an already-stressed tooth. Temperature extremes can trigger a sharp, shooting pain that stops you in your tracks.

Choosing gentler foods doesn’t cure the problem only a dentist can do that but it can meaningfully reduce your discomfort while you get treatment organised.

What Foods Should You Avoid With a Toothache?
Sugary and Acidic Foods
Sugar is the enemy of a sore tooth. It feeds the harmful bacteria already present in your mouth, creating an acidic environment that worsens inflammation and accelerates decay. The Queensland Government’s oral health guidelines highlight frequent sugar consumption as a direct contributor to tooth decay. Lollies, soft drinks, flavoured yoghurts, and even fruit juices are worth avoiding. Acidic foods like oranges, lemons, tomatoes, and vinegar-based dressings compound the problem — acid wears away enamel and stings exposed or sensitive areas. Skip sour and citrus foods until things settle.

Hard, Crunchy, and Sticky Foods
Hard foods — nuts, crusty bread, raw carrots, crackers, chips — put direct pressure on already-sensitive teeth. If your pain is from a cracked tooth or a cavity, biting down hard can go from uncomfortable to genuinely alarming very quickly. Sticky foods like toffee, caramel, dried fruit, and chewing gum cling to teeth and are difficult to clean away. They get into cavities, sit against the tooth, and give bacteria exactly the environment they need to thrive. Give these a wide berth while you’re in pain.

Very Hot or Very Cold Foods
Temperature extremes are a classic toothache trigger. A sip of hot tea or a spoonful of ice cream can send a jolt of pain through an already-irritated nerve. This happens because the pulp inside the tooth expands or contracts with temperature changes and when it’s inflamed, it has nowhere to go. Stick to foods and drinks at room temperature or just slightly warm. If you do drink something hot or cold, try using a straw to keep it away from the affected tooth.

Alcohol and Spicy Foods
Alcohol dries out the mouth and introduces acidic compounds that irritate inflamed gum tissue. The Australian Dental Association notes that alcohol consumption can contribute to tooth decay, erosion, and oral complications. Save the glass of wine for when your tooth is sorted. Spicy foods can cause a burning sensation in already-sensitised gum tissue and may inflame the area further. Go for mild, plain meals while you’re healing.

What Are the Best Soft Foods to Eat When Your Tooth Is Sore?
The aim is to get adequate nutrition without putting pressure on your sore tooth. Here are some reliable go-tos:

Mashed potato:
Soft, warm, and filling. Easy to eat on either side of the mouth and gentle on sensitive areas.

Scrambled eggs:
Light texture, no crunch, and a solid source of protein. One of the easiest meals when you’re in pain.

Plain yoghurt:
Choose an unsweetened or low-sugar variety. It’s soothing on inflamed gums and requires no chewing at all.

Warm soup:
Stick to broth-based or blended soups without chunks of hard vegetables. Avoid anything spicy or very hot.

Porridge:
Oats are soft, filling, and genuinely kind to sore teeth. Add a small amount of honey if needed, but skip any nuts or seeds.

Smoothies:
A great way to get fruit and nutrients without biting. Use soft fruits like banana, mango, or avocado, and avoid citrus or anything very cold.

Steamed vegetables:
Cooked until soft, vegetables like zucchini, carrot, and sweet potato are easy to eat and nutritious. Raw versions, however, are on the avoid list.

Cottage cheese and soft cheeses:
Low in acid and easy on the teeth. Cheese actually has a mild protective effect on enamel, making it a smart choice.

Rice and pasta:
Well-cooked and served soft, these are mild, filling, and easy to eat without aggravating a sore tooth.

Can the Wrong Foods Make a Tooth Infection Worse?
Why Sugary Foods Are Especially Dangerous With an Infection
If your toothache is caused by an infection or abscess, food choices become even more important. Sugary foods directly fuel the bacteria responsible for the infection, and the resulting acid environment can accelerate damage to surrounding tissue. According to the Australian Institute of Health and Welfare’s oral health data, dental caries remains one of the top contributors to non-fatal disease burden in Australia — much of which is driven by diet.

If there’s any chance your tooth pain involves an infection look for swelling, a bad taste in your mouth, or pain that radiates to your jaw or ear you may need root canal treatment or another form of prompt care. An untreated infection won’t resolve on its own.

How to Eat Safely While You Wait for Your Appointment
While you’re waiting to be seen, eat on the opposite side of the mouth from the pain whenever possible. Rinse with warm salt water after eating to clear food debris and reduce bacteria around the affected tooth. Use a soft-bristled toothbrush and be extra gentle around the sore area.

Over-the-counter pain relief like ibuprofen or paracetamol can help manage discomfort — follow the dosage instructions on the packet and avoid applying anything directly to the tooth itself.

How Long Should You Wait Before Seeing a Dentist About a Toothache?
A mild ache that comes and goes for a day or two isn’t unusual but some symptoms shouldn’t wait. See a dentist promptly if you’re experiencing:

Toothache that has lasted more than two days without improving
Swelling in your cheek, jaw, or gum
Fever or a generally unwell feeling alongside the tooth pain
A bad taste or bad smell in your mouth
Pain radiating to your ear, jaw, or neck
Difficulty opening your mouth or swallowing
These can all be signs of an infection that needs treatment. Our emergency dentist team is available for urgent appointments we’ll get you in as quickly as possible.

Conclusion
When you’ve got a toothache, what you eat can either add to the pain or give your mouth a chance to cope while you get proper care. Avoid sugary, acidic, hard, sticky, and temperature-extreme foods. Lean on soft, mild, room-temperature options like mashed potato, scrambled eggs, porridge, and soup.

Most importantly, don’t ignore the pain. Toothaches are your mouth’s way of telling you something needs attention — and the sooner you address it, the better the outcome.
