2. My tooth hurts. I think I ... (shouldn't/ought to) see a dentist.

Resolution

• 2. My tooth hurts. I think I ought to see a dentist. (This expresses a recommendation or advice for a situation where it's a good idea, 'ought to' is slightly more formal than 'should' but fits well here for advice).

Translation (RU)

• 2. У меня болит зуб. Думаю, мне следует обратиться к стоматологу.
