If cold and heat hurt, does that definitely mean a cavity?

Not necessarily. Pain to cold is also a common presentation of cracked teeth. A practice-based study cited in a position statement covered 2858 teeth from 209 dentists; 45% of cracked teeth were symptomatic, with pain to cold in 37%, biting pain in 16%, and spontaneous pain in 11% (the original says only “2858 teeth” and does not state whether all were cracked teeth; this card follows that wording and does not infer more) [F13]. Dentine hypersensitivity is also a diagnosis reached only after other possibilities are excluded [F10]. Thus, “cold/heat pain” is a starting point for distinguishing causes, not a conclusion [F13][F10][F3].

If pain keeps me awake, can I just manage with pain medicine?

First check the levels: if swelling is expanding; swallowing, speaking, breathing, or neck signs appear; you clearly cannot open your mouth properly or cannot judge the severity; facial or jaw pain appears; tooth pain comes with chest tightness, cold sweats, or shortness of breath; or you have fever, malaise, or swollen lymph nodes, go immediately to an emergency department or urgent-care facility [F15][F17][F19][F2]. If none of those immediate signs is present but you have broad swelling not observed to be still expanding or isolated less-than-severe limited mouth opening, seek care the same day; if assessment cannot be arranged, use emergency or urgent care [F15][F17][F2]. If neither level applies, medication is still a clinician's decision; this card gives no medicine name, dose, or use advice. The literature position is that initial treatment for symptomatic apical periodontitis and acute apical abscess removes the source of inflammation or infection locally, with systemic antibiotics recommended only for spreading infection or systemic involvement [F15]. The Cochrane review found no study comparing antibiotics and placebo without surgical intervention [F15]. For irreversible pulpitis, another Cochrane review concludes that evidence is insufficient to determine whether antibiotics reduce pain [F16].

Q: What does cavity pain feel like?

There is no single answer: different problems can feel very similar, and feeling alone cannot tell which one it is. The literature can say that short, sharp pain triggered by cold or heat is a typical description of pain related to exposed dentine, and that the term itself is a diagnosis of exclusion [F10]; spontaneous pain without a trigger is used in the literature for situations associated with symptomatic irreversible pulpitis [F9][F8]; and symptomatic apical periodontitis and acute apical abscess are recorded as common causes of dental pain arising from inflamed or necrotic pulp or an infected root-canal system [F15]. Which situation is yours requires dental examination and imaging [F3].
