Uy, mama, for anything medicine-related during pregnancy, even topical sprays, kailangan talaga ng go-ahead from your OB, hindi kami sure-sure dito! Please message your doctor ASAP or call your clinic, especially at 27 weeks; they'll know exactly what's safe for you and baby. Toothaches are the WORST (been there, preggy brain + sore teeth = chaos), pero mas okay na walang guessing game when it comes to meds, di ba? Hubby ko daw ang best solution ay ice chips at prayers lang, haha, pero seryoso, doctor call na!
