Hello,
I can understand your concern.
Metallic taste in mouth can occur due to more than one reasons, but abdominal condition or
Miralax is not responsible for its occurence. It is just a co-incidence that your daughter is experiencing it while suffering from abdominal troubles.
A very common cause of this taste is poor
oral hygiene. It is possible that your daughter did not feel well for some time so she could not pay attention to adequate oral hygiene. Due to that,
plaque and calculus may have accumulated in the gums causing this taste. If you visit a
dentist, he/she will mechanically clean the plaque and calculus with scaling procedure and your daughter will find relief in the problem.
In addition, many medications and
multivitamin supplements can also cause this problem. So if she is taking any other antibiotics or medicine, I advise you to discuss their side effects with prescribing doctor and see if metallic taste in mouth is one of them.
Also,
sinusitis is responsible for this sensation in mouth. If your daughter is suffering from sinusitis currently, then this sensation can be expected till the condition is cured. One more condition is presence of cancer that can cause this problem but diagnostic tests have cleared your daughter of it so you do not need to worry about it.
Till then, she can find relief with the use of mouthwash and better oral hygiene measures. She can also suck on sugarless flavored candies.
I hope this information helps you. Thank you for choosing HealthcareMagic. I wish your daughter feels better soon.
Best,
Dr. Viraj Shah
