I'm getting several cavities filled and possibly a root canal done on the same day. My dentist suggested storing up my milk now and pumping and dumping for a day or so after he does the work. He said the novocaine isn't supposed to be harmful to babies, but just to be safe I can use the stored up milk.

Ds is 3 mo. and has never taken a bottle, so I can't completely bottle feed him for a couple of days. I'm thinking I might pump and dump once, but I'm wondering when the best time to do it is. Right when I get home from the dentist? Would drinking a lot of water after the dental work be the best way to flush the novocaine out of my system? Is any of this even necessary?

TIA

I doubt the novocaine would be harmful--isn't it used routinely in hospitals on birthing women (e.g., for numbing prior to tear repair)? You're not doing mercury fillings, right? Not sure what else one would worry about. I think in your position I'd continue to nurse. Giving bottles to an EBF baby can be tricky and stressful so probably not worth it of there's no good reason for it. Medical professionals tend to (1) know very little about breastfeeding and (2) not value it highly and think it's not really necessary.

Best wishes for your upcoming treatment!

My dentist looked up the half life of novicane. It stays in your system for 4 hours. So you should pump and dump at least once and wait to nurse till it has been 4 hours.

It's good to know it's not very harmful. My dentist admitted he didn't know how long it would take the novocaine to get out of my system or how harmful it would be. He does really support breastfeeding, though.

Thanks for letting me know this. I will pump and dump when I get home and try to wait 4 hours if he will take the bottle.

I wouldn't bother pumping and dumping. if it's half life is 4 hours (even assuming it's an issue), just waiting would do it too.

they routinely use it for repairs in the hospital, and it's a local, not systemic, medication. locals are pretty reliably non-issues.

Never did, didn't even consider it, dentist(s) never even suggested it.

It's FINE. No reason to pump and dump at all.

Just as a further point of information, Novocaine is an L3

L3 MODERATELY SAFE:
There are no controlled studies in breastfeeding women, however the risk of untoward effects to a breastfed infant is possible; or, controlled studies show only minimal non-threatening adverse effects. Drugs should be given only if the potential benefit justifies the potential risk to the infant.

Unfortunately, I cannot find my Hale's guide, so I don't know what the pediatric concerns are.

Lidocaine (xylocaine) is an L2.

wow... pumping and dumping is not necessary. I'm surprised at the responses you got here. First of all, novacaine is an L3, which means it is moderately safe. According to Thomas Hale (medications and mothers milk), who is the only person to research drugs and lactation, it is a localized drug, not a systemic drug, and very little if any is likely to reach breastmilk. It is rapidly metabolized, and the half life is 7.7 MINUTES. IT also has a larger molecular weight, which makes it less likely to cross plasma membranes into mothers milk. When it is mixed with epinepherin, which allows it to work longer and more effectively (and also allows you to give a lower dose than without) can up the half life to 2 hours. As the drugs leave your local area and the blood stream, they also leave your milk. If you feed right before your procedure, you should be ready to go afterwards.

...caine, particularly with epinephrine, sticks in the local tissues for some time and then slowly transfers into the plasma compartment. It is rapidly cleared by the liver.

There are no pediatric concerns reported via milk.

How would the novocaine even get to your breasts? Think about how this drug works- it's injected into the area that needs to be numbed, and the medication stays where it's injected. How else would it only numb one portion of your mouth? If the novocaine can't even go from the left side of your mouth to the right, how could it get into your milk?

Ok. Thanks, everybody. I'm not going to bother with the pumping and dumping.

And to answer a previous question, no they won't be mercury fillings. The composite is not so healthy either, I know, but it's better than mercury.
