Oral thrush getting worse is that a sign it is going away i got it from amoxicillian and have been using peridex (chlorhexidine gluconate) and also apple cider vinager?

No: Yeast infection of mucous lining of the mouth and tongue can happen after antibiotics. Be seen by doctor/ dentist to confirm diagnosis & get proper treatment which can be far more effective than what you have been trying. Peridex (chlorhexidine gluconate) is Chlorhexidine gluconate --an antibacterial--& and would not help in thrush; probably just make it worse. Add probiotics lactobacilli (good bacteria) instead, & go in.

Antifungal: I would check with your doctor to see if they might want to add some form of antifungal medication to your treatment(such Mycelex (clotrimazole) troche you can let dissolve in your mouth or an oral rinse other than Peridex like nystatin).

Thrush: Abx can knock out a lot of bacteria resulting in the fungus taking over, what you may want to try is replacing some of the good bacteria you lost, which will in turn balance out the fungus. Try otc options like supplements or milk that are enhanced with bacteria. In the future take it when you are on an abx. Try antifungals and less things that kill more bacteria like peridex (chlorhexidine gluconate).

Treat for Fungus: If it truly isthrush, then it is a fungal infection and needs an anti fungal medication to get rid of it. There are rinses and lozenges that are very affective. They are prescription so you need to see a dentist for treatment. The cause is a yeast and they typically like acid environments and are opertunistic. Apple cider vinegar will make it worse. Antibiotics are what got it started.

Thrush: Nystatin – this medicine must come into contact with the yeast in order to kill it. Nystatin comes in a suspension, or liquid, and in a lozenge, also called a troche. The suspension is swished around the mouth and then swallowed. The lozenge dissolves in the mouth. Both the suspension and the lozenges are used several times a day until the lesions are completely gone.There is also fluconazole.
