PER CURIAM.
In this dental malpractice case, plaintiff appeals from the circuit court’s order granting
summary disposition to defendants, two dentists and the business entity through which they
practice. We reverse and remand. This case is being decided without oral argument in
accordance with MCR 7.214(E).
Plaintiff went to defendants’ office to have two teeth extracted. Defendant Powell
extracted one apparently without incident. His work on the other resulted in the breaking of the
tooth, leading to his administering a second anesthetic injection and attempting to extract the
remnants in pieces. In time, Powell asked defendant D’Orazio for assistance, and D’Orazio
completed the extraction. Afterward, plaintiff complained of numbness from her lower lip to the
bottom of her chin, resulting in a crooked smile and difficulty pronouncing some words.
Plaintiff’s expert testified on deposition that the cause of plaintiff’s injury was faulty
applications of anesthetic or faulty extraction techniques and opined that the latter was the more
likely culprit. Asked which of the three root extractions were done improperly, the expert
replied, “There could have been one, two, or all three roots that were improperly manipulated
and could have caused the injury,” adding that “since both doctors had a hand in the socket with
instruments in the socket, I would say that it would be impossible to assess a percentage of
responsibility.” Pressed for the relative likelihoods that the injections of anesthetic or the
surgical techniques caused the injury, the witness replied, “As far as percentages are concerned, I
couldn’t guess at that,” and added, “There are some things just unknowable about certain things,
and one of them is forensic evaluation of dental procedures that result in injuries. Some of them
-1-
are pretty cut and dry, [but] these kinds of instances are not, because you had multiple
procedures and multiple events occurring.”
The trial court granted defendants’ motion for summary disposition on the ground that
“[y]ou can’t have a jury guessing and it’s not supported by competent evidence to go to the
jury.”
This Court reviews a trial court’s decision on a motion for summary disposition de novo
as a question of law. Ardt v Titan Ins Co, 233 Mich App 685, 688; 593 NW2d 215 (1999). “In
reviewing a motion under MCR 2.116(C)(10), this Court considers the pleadings, admissions,
affidavits, and other relevant documentary evidence of record in the light most favorable to the
nonmoving party to determine whether any genuine issue of material fact exists to warrant a
trial.” Walsh v Taylor, 263 Mich App 618, 621; 689 NW2d 506 (2004).
Plaintiff argues that the evidence was sufficient to create a question of fact for jury
resolution, relying on the doctrines of alternative liability and concert of action.
The concert of action claim is a true joint tort . . . . Even if defendant
caused no harm himself, he is liable for the harm caused by his fellows because
all acted jointly.
The alternative liability theory, on the other hand, involves not a joint tort,
but rather, involves independent acts by two or more tortfeasors, all of whom
have acted wrongfully, but only one of whom has injured plaintiff. . . . Rather
than deny the innocent plaintiff his recovery because he cannot prove which of
two or more wrongdoers injured him, the courts impose joint liability on all
wrongdoers. In cases of alternative liability, a defendant is free to absolve
himself of blame and cast the entire burden on his fellows, even if it be shown
that he acted wrongfully, but that defendant must bear the burden of proving that
his wrongful act was not the cause of plaintiff’s injury. [Abel v Eli Lilly & Co, 94
Mich App 59, 73; 289 NW2d 20 (1979) (citations omitted), aff’d as modified on
other grounds 418 Mich 311; 343 NW2d 164 (1984).]
Depending on whether defendants are deemed to be acting in concert or independently,
one of the two doctrines will impose liability. It would seem the more accurate analysis is to say
that the two dentists acted in concert to extract the tooth. As this Court in Abel, supra at 72,
explained:
It is well-established that if two or more persons engage negligently in
concerted activity, and as a result plaintiff is injured, all are liable even though
only one directly caused the injury. McCoy v DeLiefde, 376 Mich 198, 205; 135
NW2d 916 (1965) (opinion of Souris, J.). Liability is imposed on all because all
have joined in breaching their duty of care to plaintiff, and he was injured as a
result of that breach.
In affirming, the Supreme Court noted that, under the concert of action theory, “a plaintiff need
only allege that the defendants were jointly engaged in tortious activity as a result of which the
plaintiff was harmed.” Abel, 418 Mich at 338.

In the case at bar, the two dentists worked together to extract the tooth. Plaintiff’s expert
will testify that both breached the standard of care and were negligent in the procedures that each
performed. Either’s negligence could be responsible for plaintiff’s injury, though presumably
only one actually directly caused the injury. Specifically, plaintiff’s expert testified that the
surgical technique of both doctors “was not consistent with what would be a surgical technique
in detail to elevate and remove tooth number 17.” The expert was also critical of the technique
used to inject the anesthetic, but concluded it was slightly more likely that the fault lay with the
surgical technique employed.
The situation described by plaintiff’s expert fits neatly into the concerted activity
doctrine. Both dentists worked together to achieve the tooth extraction and both breached their
duty of care to plaintiff. And plaintiff was injured as a result of that breach.
Even if we were to conclude that both defendants were not engaged in a concerted
activity, then the alternative liability theory would apply. The requirement under this theory is
that all tortfeasors have acted wrongfully, although only one injured the plaintiff, but the plaintiff
is unable to establish which of the tortfeasors actually caused the injury. This doctrine applies to
the case at bar because, according to plaintiff’s expert, both dentists breached the standard of
care and negligently treated plaintiff. Indeed, the illustration used by our Supreme Court in Abel,
supra at 326, from the case of Summers v Tice, 33 Cal 2d 80; 199 P2d 1 (1948), is similar in
concept to the case at bar. In Summers, the plaintiff argued that he was negligently shot at by
both of his two hunting companions, but only one shot hit him. The plaintiff was unable to
ascertain which of the two companions actually fired the shot that hit him. Our Supreme Court,
Abel, supra at 326-327, explained the decision as follows:
The Summers court agreed, as a preliminary matter, that both defendants
were at fault in having acted negligently toward the plaintiff. The court also
recognized that plaintiff had failed to meet his traditional burden regarding cause
in fact. Only one shot had injured plaintiff; both defendants could not have shot
it. Since the most the plaintiff could prove was a 50% probability that either of
the defendants had caused the injury, plaintiff had failed to establish that either
one of the defendants was more likely than the other to have caused the injury.
The court then decided—as a matter of policy—that it was preferable that
the two wrongdoers, both of whom had acted negligently toward the plaintiff and
had created the situation wherein plaintiff was injured, should bear the burden of
absolving themselves rather than leaving the innocent plaintiff remediless.
Therefore, the court placed the burden of proof on the issue of causation in fact
upon the defendants.
In the case at bar, plaintiff’s expert opines that both of the individual defendants directed
a negligent act at plaintiff, either one of which could have caused plaintiff’s injury (but
presumably only one of which actually did). This is, in our mind, the same as the two hunters
who shot at the plaintiff in Summers, both of whom were negligent but only one of whom caused
injury. Indeed, if anything the argument is stronger in the case at bar to impose liability on
defendants. In Summers, the defendant who did not in fact injure the plaintiff still would not
have injured the plaintiff even if the other defendant had not caused injury. But in the case at
bar, plaintiff’s expert’s testimony leaves open the possibility that the only reason that one of the
-3-
events did not cause plaintiff’s injury was only because the injury had already occurred. That is,
if an earlier negligent act is what caused plaintiff’s injury, then plaintiff may have still been
injured by a subsequent negligent act had the earlier negligent act not occurred. That is, it may
well be that the act which did not injure plaintiff only failed to injure her because the damage
was already done by an earlier act.
For the above reasons, we believe that liability may be imposed upon both defendants
under one or both of the theories. Of course, under both theories, one defendant may absolve
himself of responsibility by demonstrating that the other was, in fact, the cause of plaintiff’s
injury. Abel, supra at 73.1
Reversed and remanded for further proceedings consistent with this opinion. We do not
retain jurisdiction. Plaintiff may tax costs.

We also note that it is unclear to us how the trial court justified granting summary disposition to
the corporate entity. Even if the individual doctors were entitled to summary disposition because
their personal liability could not be established, because it could be established that one of the
corporation’s employees caused the injury, presumably the corporation would remain liable
under a respondeat superior theory. In any event, that issue is not raised and our resolution of the
issues that were raised renders it unnecessary to address this topic.
