Tooth pain

Several factors combine. Lying flat increases blood flow to the head, which raises pressure inside an inflamed pulp that has nowhere to expand because it is enclosed in rigid tooth structure. There are also fewer distractions at night, so pain is more noticeable. Clinically, pain that wakes you is a meaningful pattern, not just an inconvenience. Spontaneous night pain is more associated with irreversible pulp inflammation than with simple sensitivity, and it is worth reporting specifically.

Yes, and this is one of the more consequential misunderstandings in dentistry. Pain from an inflamed pulp can stop because the nerve tissue has died, not because the problem has resolved. The infection then continues silently into the bone at the root tip, often becoming apparent later as an abscess or as a finding on a radiograph. A tooth that hurt badly and then went quiet should be examined, not assumed to have recovered.

Usually not on their own. Most toothache originates from inflamed or infected tissue inside the tooth, and antibiotics do not reach that tissue effectively because it has lost its blood supply. They have a role in specific situations, spreading infection, systemic involvement, certain medical circumstances, as an adjunct to treatment instead of a replacement for it. The definitive treatment is dealing with the source, whether that is a filling, root canal treatment or extraction.

Throbbing pain alone is usually urgent instead of an emergency, meaning it warrants prompt assessment but not emergency services. What converts it into an emergency is spread: difficulty breathing or swallowing, swelling extending toward the eye, the floor of the mouth or the neck, fever alongside facial swelling, or being unable to open your mouth. Those signs mean immediate medical attention, not waiting for a dental appointment.

Yes, and it is a common source of confusion. The roots of the upper back teeth sit close to the maxillary sinus, so sinus inflammation can present as aching across several upper teeth at once. Clues that point toward sinus involvement include pain affecting more than one tooth, worsening when bending forward, and accompanying congestion or a recent cold. A dentist can test the teeth individually to distinguish this, a more reliable route than guessing from the pattern alone.

Pain that lingers after hot or cold, arrives spontaneously, wakes you at night, or is accompanied by any swelling should be assessed promptly, not monitored. Brief sensitivity that stops immediately is less urgent but still worth investigating at a routine appointment. Any of the spreading-infection signs, difficulty breathing or swallowing, swelling toward the eye or neck, fever with swelling, mean emergency care the same day.

Pain from inside a tooth localizes poorly because the pulp has no proprioceptive nerve fibres, so the brain cannot pinpoint the source the way it can with skin. Pain can be felt in the wrong tooth, the opposing jaw, or across a region. This is why diagnosis relies on testing, cold, percussion, bite tests, radiographs, comparing the suspect tooth against its neighbors, instead of on where you point. It is thoroughness instead of uncertainty.

Indirectly, yes. Stress is strongly associated with clenching and grinding, which can inflame the ligament around a tooth root or aggravate an existing crack, producing pain that feels worse during stressful periods. Stress does not create decay or infection on its own, but it can intensify how existing dental problems are experienced and can contribute to a grinding habit that causes new ones.

The response to cold is genuinely diagnostic. A brief sharp pain that stops the instant the stimulus is removed is typical of exposed dentine or reversible pulp irritation. Pain that lingers for tens of seconds or minutes after the cold is gone suggests the pulp inflammation is more advanced and less likely to settle on its own. Reporting exactly how long the pain lasts after the trigger is removed is more useful than describing intensity alone.

Yes: referred pain from a back tooth, particularly a lower molar, can be felt in the ear, temple or side of the head because of how the nerve pathways in that region overlap. This is one of the reasons dental causes are sometimes missed when someone first seeks care for ear or headache symptoms, and it is worth mentioning any tooth symptoms at all, even mild ones, if you are being assessed for pain in that area.

Yes: gum inflammation, an impacted piece of food pressing on the gum, a recently placed filling still settling, referred pain from the sinuses or jaw joint, and even unrelated facial pain conditions can all produce sensations that feel like toothache. This is exactly why a structured examination comparing the suspect tooth against its neighbors matters more than assuming the cause from the symptom alone.

Taking your usual over-the-counter pain relief according to the label is reasonable, but avoid masking the pattern entirely right before you are due to describe it, since an accurate account of triggers, duration and timing genuinely helps diagnosis. If pain relief is not touching the pain at all, that itself is useful information to report, not something to push through silently.
